It was (is) All About the Medium

Kodachrome 25; 1990s

For potentially bored readers, I have some good news. I just returned from another European trip in October, which means some new images again, rather than my historical stroll down memory lane. I am post-processing images right now. But first, another reminiscent post:

Kodachrome, was simply the standard by which any other choice was measured. And until the 1980’s they generally just didn’t measure up.

My “evolution” series got me thinking a bit about the medium. Those who have been shooting only during the past 20 years may be vaguely aware of an old cellulose material called film. When I jumped in, film was all we had, and the “pickins” were slim.  If you wanted to shoot color slides (the medium of choice, it seems, for serious “nature” photographers), you mainly had Kodak. There were competitors, but in the early years, Kodak dominated the film world, for a number of reasons. Most shops and retail stores stocked Kodak products.

In the Beginning, God created the Heavens and the Earth ….. and Kodachrome

Perhaps the most important reason was that Kodachrome, was simply the standard by which any other choice was measured. And until the 1980’s the others generally just didn’t measure up.

prior to about 1936, color photography was not prevalent among all but a limited group of professionals. Color wasn’t really that great (though it was relative, I suppose). Early results (including some early color slide films) are reminiscent of the early “colorized” movies we saw. We all knew it was black and white with some color added. In my mind, this was true until Kodachrome became the standard.

In 1936, a couple of musician-turned-scientists were hired by Eastman Kodak to complete their experimental process. As I did my research, I was interested to learn that there actually was another “Kodachrome,” which was a 2-color process, developed by a Kodak engineer in 1913. In 1936, Kodak introduced the 3-layer process which became the vaunted Kodachrome. Called a non-substantive film (an odd name in my view – but addressing the lack of dye or colorant “substances” in the film emulsion itself), the Kodachrome process was complex. It was essentially a B&W film, in which color dyes were added to the 3 different layers during the development process.

Fuji Velvia

This meant that a specialized processing setup was necessary, and until 1954, Kodak successfully maintained a monopoly on this process (known as K-14), by selling Kodachrome only with pre-paid processing by Kodak as part of the deal. In 1954, the United States challenged this practice as an anti-trust violation, and an agreement was entered into, among other things, ending this practice (and of course, allowing competitors to acquire the accoutrements to develop Kodachrome).

Originally, Kodachrome was released at ISO 10. A 20-exposure cassette cost $3.50. That, for those interested, would have been about $65.00 in 2019 dollars!

Kodak (Ektachrome) E100SW

In 1936, there was no ISO (or ASA, as it was originally known). During the World War, the military wanted a single standard to be able to increase their efficiency. Prior to this time, there were several standards (and thus, several different marketed light meters – all handheld in those days). The American Standards Association created a “standard” measurement for light sensitivity measurement, which then became known as the film’s “ASA,” or ASA rating. In 1987, the International Organization for Standardization was created and film manufacturers worldwide shifted to this international standard (which is numerically identical to the old ASA standard). So we now refer to light sensitivity measure – on all media – as “ISO.”

There were non-believers …

That same year (1936) German film and camera manufacturer, AGFA, introduced Agfacolor. While very similar to Kodachrome, including its three layer emulsion, AGFA engineers embedded color dyes into the film emulsion, making the development process less complex. I shot maybe one or two rolls of Agfacolor. Didn’t care for it. It looked, as I noted above, like lightly colorized black and white. It did seem to make a big hit in the motion picture industry, however, and was widely used in film-making for a number of years.

The Fujifilm company was established in Japan in 1934. I was not able to find much about early film offered by Fuji. Of course, they catapulted into top status with the release of Velvia, years later.

Fuji Velvia

Kodachrome II, was introduced in 1961, with an ASA/ISO rating of 25. In 1962, they a released 64 ASA version (later they simply became known as K-25 and K-64). In 2007, K-25 production was discontinued. K-64 production followed suit in 2009). One source noted that in 2009, sales of Kodachrome made up 1% of Kodak sales revenue. Kodak had essentially ceased processing Kodachrome themselves by 2006, and by 2010, the only one Kodak-certified facility remaining was Dwayne’s Photo, in Parsons, Kansas. Later that year the even they ceased Kodachrome processing. Which led me to wonder, what if I had any rolls of undeveloped Kodachrome? Some “Google” research will reveal that there are processors out there who claim to be able to process it. But I checked my freezer. No film of any kind in there. Phew! 🙂

Nothing lasts forever …

In addition to its complexity and considerable expense, there were other Kodachrome drawbacks. Transparencies were designed, of course, to be projected with a relatively strong light (anybody else remember those “travelogue” slide shows that were prevalent in the 1960s and 1970s?). The medium was consequently, relatively high contrast with lots of shadows. This made it particularly touchy to produce photographic prints from. And, we have learned in later years, the process of scanning and converting Kodachrome to digital images often is challenged by colorcasts which need to be addressed in the scanning process.

Stemming partly from photographers (particularly consumers) demand for cheaper and more convenient products, and also partly borne out of the 1954 antitrust decree directing Kodak to endeavor to release a newer, more consumer-friendly film that was in development, Ektachrome, with a new “E-process” in which dyes were embedded in the film emulsion was introduced in 1955. Originally ASA 32, a 160 version was introduced in 1959, and 64 and 100 ASA versions in 1977. I wasn’t even shooting yet! Two years after I got started, in 1979, Ektachrome 400 was released.

Kodak Elite Chrome 100

Ektachrome had some advantages. It was cheaper than Kodachrome and cheaper and easier to process. You could have it processed locally. If you wanted to make the investment in color processing equipment (essentially, some relatively affordable tanks and chemicals), you could process it yourself.

I shot very little of it. This was probably partly due to the prejudice I acquired early on, from my shooting inspiration. But there was also still no doubt that Kodachrome was still the professional-preferred medium for most. Ektachrome also had a known blue color cast, and I found it cool, and a bit less saturated than my personal taste. So, throughout the 1970’s and 1980’s I shot Kodachrome.

Kodak Elite Chrome II (50)

When I came back to serious shooting in the early 1990’s, the industry had changed. Fuji introduced its Velvia 50 in 1990. Its characteristic was a very colorful, saturated, and contrasty profile. It took aim at Kodachrome and punched it in the face. It quickly became the slide film of choice for nature photographers – especially for landscape and flowers. And it used the E-6 process (by this time virtually every emulsion used the E-6 process, except for Kodachrome).

Again, while there were others, there really weren’t 🙂 . Fuji and Kodak went head to head. Fuji released Velvia. Kodak parried with Lumiere 100 (a neutral balanced Ektachrome) and Lumiere 100X (a warm-saturated Ektachrome). Fujia added Velvia 100. Lumiere was short-lived and said by some to have some inconsistency in color from roll to roll. Kodak replaced it with E100S (saturated), E100SW (warm saturated) and E100VS (very saturated – Kodak’s answer to Velvia).

Kodak Elite Chrome II (100)

Fuji, in 2003, in response to criticism that Velvia was just too colorful (perhaps unrealistic to some), introduced Provia, in 100, 200, 400, and 1600 ISO versions, and  Provia F (ultra-fine grain).

These were all so-called “professional” films. They tended to be more expensive. Whether they were that much better is probably a personal judgment. They probably had better quality control. I remember going to my photo shop in my community to buy these films (they weren’t generally available in the big box and drugstores), and they were generally stored in refrigerated conditions.

To cater to consumers, both companies released (almost simultaneously) “consumer” versions of the above film varieties. Kodak’s Ektachrome became Elite Chrome, Elite Chrome II, and Elite Chrome Extra Color.

Fuji Sensia II

Fuji’s consumer version of Provia was Sensia, Sensia II, and Sensia III, in various ISO ratings. I am not aware that they ever marketed a consumer version of Velvia.

Interesting stuff for some of us, and by the mid-2000’s, essentially irrelevant to most of us. 🙂

Fuji Sensia II (100)

Before I did the research for this piece, I spent a few hours going through my archives to find examples of some of my images made with all of the above media. The problem is that it is truly impossible to make comparisons, here. This is partly because in order to do this on a blog, it became necessary at some point to convert all the media to one single media: digital. So this may not have been a very useful exercise – but it was fun doing it. Presented as digital media, I can see some nuances, but not any huge differences (of course, post processing software has “recipes” to “recreate” film “looks” in digital post-processing these days. I have done very little of that, except for B&W, and cannot really say how accurate they are). I did very little post-processing of the “film” images; just a bit of sharpening mainly. I would be interested if you can see any difference.

For me, digital processing made everything possible; digital capture made it much more convenient


And there shall come a Rapture …..

Digital shifted the focus (see what I did there?) from all of the considerations of film, down to one thing: the digital sensor. And it is all about the quality, sharpness, and resolving capability of those tiny little electronic chips. We moved from cost and technical ability to manufacture affordable digital sensors, to “size” matters, and then back again these days to the fact that maybe it doesn’t even matter so much any more.

Nikon D100 (2002)
6 megapixel – “APS”

The Purple Coneflower is one of my first flower images made with direct digital capture. As noted above, it is difficult to make useful comparisons with film. First, doesn’t scanning a film image convert it to a “digital” image? Then, once we get into the post-processing world, everything we once knew kind of goes out the window. We can post-process a film scanned image in much the same ways we can post-process a digital capture. It may be possible to capture “cleaner” images directly, but we still have to deal with “digital” grain (noise). Color rendering becomes pretty much what you want it to be. One interpretation of the coneflower, for example, is that it has a “color-cast.” This is purposeful on my part because I like the warm, saturated color in many of my more colorful “nature” images. But I did this (of course, you can inadvertently capture color-casts, but if you shoot in the raw format, you can almost always correct, or adjust it, as can be seen from the white daylily image made with the Nikon D200).

Nikon D200
10 Megapixel; APS

I had to laugh as I reviewed digital images in my Lightroom Catalog. I apparently have an affinity for lilies, probably because they are an easy, plentiful, and colorful subject (emphasis perhaps on “easy” 🙂 ). In any event, I have almost 400 lily images. The closest second is around 25.

We moved from cost and technical ability to manufacture affordable digital sensors, to “size” matters, and then back again these days to the fact that maybe it doesn’t even matter so much any more

When I shifted to digital, I was satisfied with what was available, but not completely happy that the sensors were still small. Size, with sensors, had at least three dimensions: actual physical sensor size, and pixel depth (the number of pixels on that space), and the actual physical size of each individual pixel. Obviously, they are interrelated. And in the beginning, this was a pretty big deal. Larger sensors and larger pixels could handle capture with less noise, at higher ISO levels and more detail. So, almost from the beginning, there were “pixel wars” between the purveyors of digital cameras. But also in the beginning, the successful manufacture and hence, availability of larger sensors was prohibitively expensive. Of course, the sensor size itself also effected the optics in a big way. The 35mm SLR camera had become the sort of “standard” by which most of this stuff was measured. But the affordable sensors at first were the so-called “APS” sized sensor, which is significantly smaller than the 35mm film rectangle we were used to, but as you can see by the gold rectangle below, much larger that what we first had with Point & Shoot cameras.

Sensor Sizes Compared

APS sensors meant that the lenses made for the 35mm perspective, did not work the same way. There were pros and cons (covered ad nauseum by others elsewhere). Because of the perceived combined “advantage” of a higher-quality capture and regaining the use, especially, of their wide angle lenses, many 35mm users almost immediately began to call for a so-called “full frame” sensor. I have always found this kind of illogical. What would a “medium format” (4 x 5 inch), or a full 8 x 10″ view camera user call a sensor made to their size? :-). But “full frame” caught on. I eventually jumped on that train, believing “full frame” capture was necessary for me to achieve the image quality I desired. I want to emphasize that there is certainly nothing negative about owning the larger sensor. There is little doubt that you can coax more out of it than the smaller sensors. But to me, it may have been the purchase of a dump truck, when a small pickup (or even a wheelbarrow) was sufficient. There are a couple factors – all empirical for me – that bring me to this conclusion.

D800 “full frame”

First, I had some personal experience. While I am not sure this is any longer true, at the time, to me the “holy grail” was the photographic print, on traditional photographic paper. I have owned a couple Epson printers that were capable of making inkjet prints that rivaled anything I had ever received from any lab. And, I was able to do my own “darkroom” adjustments. For economic reasons, the largest I generally made were 13 x 19″ prints, and that became my de facto standard for measuring quality. And while I enjoyed and appreciated my “full frame” Nikons, my “testing” didn’t prove out the benefit (for me) of the larger sensor (except, perhaps with its integration with some really fine pro- zoom lenses designed for 35mm).

(equivalent to Nikon APS)

The real eye opener came some years later, when I made side-by-side images with my Sony “full frame” and my Sony RX100, and printed them. I could not see much difference. To be fair, much of what has gone on has been in the post-processing realm (both in terms of technology and my abilities). There have also been technology gains which have made the smaller sensor just that much better.

Zeiss 50mm f1.8 lens


The red lily image illustrates this, I think. It prints beautifully as a 13 x 19. I believe it could easily print much larger with no noticeable degradation. It illustrates to me my earlier premise that resolving power, low light, and clean capture-capable sensors (regardless of size, and often regardless of the number of megapixels) has really become the “media” of today.


A Comparison; DSLR / Mirrorless

What can I say? I am in a “gear” mode these days. I know this isn’t the first time someone has compared the two.  But mine might be more like a rambling muse 🙂  (again, you might want to look at my page describing my gear reviews to see how I come at this. I leave the heavy lifting to the pros).

I have had some “back and forth” discussion with several of my friends over the past few weeks, about my switch from Nikon DSLR to Sony MIL gear (Sony also “plays” in the DSLR world, but in my view, doesn’t offer any reason for a “seasoned” non-Sony DSLR user/owner to consider a change from their current gear).

The seed was planted that maybe we could achieve “pro” results in a small, light package

The “world-changing” event came through Sony’s mirrorless interchangeable lens system (MILS) bodies. They were not the first to the table. Olympus has made a pretty big splash with its 4/3 system; well-made stuff and great glass. Nikon has its own proprietary size sensor MIL system (which has always left me scratching my head). Fuji has a nice system (using an APS sized sensor) and is probably the closest “apples/apples” competitor to the Sony System (Leica offers an APS sized MILS system, also, but its — well — Leica). My draw to Sony’s system was probably logical enough. Sony manufactured (perhaps still does) the sensors Nikon used in its DSLR lineup. Sony also offered the ability (primarily through 3rd-party adapters) to use my Nikkor lenses on the body (albeit as MF only lenses); and as I “grew” into the system, the availability of glass manufactured either directly by Zeiss Optical, or in a partnership between Sony and Zeiss, which created “Zeiss-quality” glass and more importantly look and feel (there is no doubt some debate about whether the partnered lenses — which are built by Sony — are as good as the pure Zeiss.  I owned and used both on my NEX-6 and I couldn’t see a difference).

2012.  Sony’s early offerings were their “NEX” line of cameras, using APS – size sensors (Sony has discontinued the name “NEX” in favor of what they deem their more consistent “Alpha” naming scheme.  The newest available iterations are basically the same body style, with some “improvements” – more later). Ironically, the Sony NEX-6 which I first acquired in 2012 (and still own and use regularly) had the same Sony-manufactured APS-size sensor as the very good Nikon D7000 DSLR I owned at the time as a backup.  I traded it and for a time, I carried the NEX-6 as an all purpose travel and walk-around camera and backup to my Nikon DSLR system. I kept the Nikon D800 and glass for my “more serious” shooting.

I fell in love with the Sony-Zeiss 24mm 1.8’s buttery bokeh

As I began to experiment with some of the fixed focal length glass offerings for the NEX, I fell in love with the Sony-Zeiss f1.8 24mm lens and its buttery bokeh.  The seed was planted that maybe one could achieve “pro” results in a small, light package like this (it is a thought almost “retro” to the old rangefinder cameras used by some pretty amazing pro photographers years ago).

2013. Along came the a7 “full frame” series. The a7 sports a 24mp 24 x 36 “full frame” sensor, and the a7R, features the same 36mp 24 x 36 “full frame” sensor (including the lack of AA filter) that resided in the top-of-the-world, Nikon D800e! All in a small (it turns out, “smallish”) mirrorless body which was reputed to be pro-like in build quality. How could we resist?

It Begs a number of Questions

And it begs the question.  It actually begs several of them. Some of them have been asked and answered. How many megapixels do we need? I have come to the conclusion that 36 is overkill for most of us. Do we need “full frame?” In my view, that may be the real question. And, the burning question: can we have a full frame, DSLR-equivalent shooting experience in a smaller, more portable (and possibly less expensive) package? Lets try to answer a couple of them — Not necessarily in the order asked.

1.  Can Mirrorless Full Frame Compete with DSLR Full Frame?

Lets start with the big one. Following the lead of a couple of my friends, I did some “quick and dirty” comparative research. This is not scientific. I used B&H pricing and the specifications published on their catalog site. I rounded. But I don’t think the rounding error will be significant enough to skew the result. I will use my “default” “kit” (as the Europeans like to call it). I carried (for the most part) a Nikon D800 body with a 24-70 f2.8 and a 70-200 f2.8, and a large enough tripod and head to support that gear. The camera and lenses will cost you $7,600. An equivalent A7r, 24-70 and 70-200 setup will cost you $6,800. That $700 would buy a pretty nice tripod, or another piece of glass.

It’s not apples/apples

However, its not apples/apples here. First, the “equivalent” lenses are maximum f4, against the f2.8 apertures of the pro DSLR lenses. Is the added bokeh worth $350 a lens? Maybe. It’s pretty important.  I have to say that I was “wowed” by the difference between f2.8 and f1.8 when I first shot the NEX lenses.  Also, I have compared the two 70-200 copies. They are not “equivalent.” The Nikkor IQ is palpably better, in my view in that lens. With the 24-70 (Zeiss quality glass), the two are virtually indistinguishable (again, not a pixel peeping, scientific comparison – just my “feel”), but the Nikkor can produce slightly nicer bokeh in many cases, with its maximum f2.8 aperture.

And there is a non-lens comparison issue that for some is huge (for me, not so much). According to Nikon, its digital camera engines produce a true 14 bit “lossless” raw file. The Sony cameras do not! The raw file from the Sony “engine” is apparently partially processed – presumably to save some size? It can, in some cases, produce artifacts which Nikon and Canon’s raw files are said not to have. At least at the pixel peeping level, for the serious bits and bytes squashers out there, this just might be a deal breaker. Seems like it is easily enough addressed by Sony, if they choose to (and in my view, they should).

There is a perhaps, more apt comparison. The newer Nikon D610 sports the same “full frame” 24 x 36 24mp sensor as the Sony a7. Trade out the D800 for the D610 and your total cost goes to $5,000 for the Nikon rig. Trade out the a7 for the a7r and your total Sony cost is $3900. Is the $1,100 difference worth it? Is it really $1,100 (what if you “live” with the 24mp D610 and the Nikkor glass and now have a less expensive setup than the “best” Sony?). Some of this goes back to my first question above. Do you need 36mp? I think that for the vast majority of us, the answer is no.

The Nikon rig weighs a total of about 7.5 lbs. The Sony rig: about 3 3/4 lbs

Here’s where it gets interesting. My “premiere” Nikon rig weighs a total of about 7.5 lbs. The Sony rig: about 3 3/4 lbs. And that does not take into consideration that you can probably go with a smaller, lighter tripod with the smaller, lighter gear. And there is also a difference in overall size. The body is smaller and the lens barrels shorter and slightly smaller in diameter. As I write this, the a7 and 24-700 sit next to me on the desk and I am struck by how similar in size it is to the old, familiar Nikkormat camera with a 50mm lens attached that I shot for many years.

So, does size really matter? I think the answer is no different than it has always been, when the issue has been about gear: It really depends on your intended use, and your travel parameters. I have noted on other blog posts that the Sony setup I use is very suitable for general purpose use; as I use it. Travel, stills, landscape and the like all lend themselves to this rig. For wildlife, sports, etc., I do not think it is there. If I were going to do bird or wildlife shooting, or sports shooting, I would probably lean in the direction of the D610 (or better) setup above. I do think that except for very exacting specification shooting, 24mp is more than adequate and for reasons I will discuss below, probably preferable to the 36mp sensors. But if you shoot like I do, and size and weight are a real factor, then less than 1/2 the weight, and noticeably smaller in size to make it very attractive.

2.  How many Megapixels Do You Need?

As the digital revolution has now passed us by, so, too probably have “Megapixel Wars.” My first DSLR (the D100) was a mere 6mp.  Yet, I have 24 x 36 prints that are pretty impressive, from shots taken with that “dinosaur.”  But as with all “bigger is better” kind of things, there comes a logical point of no return. I think the digicam industry has taken us there, and we are coming back to the field.

Before we can really address the “right” number of megapixels, I think we need to put “size” into perspective. Megapixels is just a number. In an oversimplified way, it is just a measure of the number of photosites on a given camera sensor. If I put 36 megapixels on a 24 x 36 chip, I am going to get a far different result than if I put 24 on there. In the latter case, if 36 sites fit on it, I will either have significant gaps with the 24 example, or I will have to make the 24mp photosites bigger themselves, to fit the space. Of course, it is the latter that is the case, and in terms of every measure except perhaps detail, these bigger photosites are actually going to yield a more pleasing result. This is because of physics and electronics way above my pay grade. But for these reasons, under most circumstances, I believe the 24mp will yield cleaner, more noise free results. The advantage: better low light imagery, and probably just overall cleaner images.

I think 36 megapixels is overkill

Even more important for general use; this will be a more “forgiving” sensor. Because the 36mp chip in the D800 and a7R is capable of resolving significant detail over “smaller” sensors, it will also show more of your “warts.” If your glass is not very high quality, the result is likely to be “highlighted” weaknesses of the glass. If your shooting technique is lazy or poor, your weaknesses will show up in a magnified way. In that sense, the 36mp sensor is really best suited for a painstaking professional with high quality lenses, painstaking and expert technique (read: locked down on a steady tripod, remote release, good technique and mechanics to avoid movement and vibration, etc.). For general purpose, it will probably not enhance – and could very well hinder – your photographic results.

And, of course, the files are huge. That means slower post-processing and more computer power and storage memory needed. So what would be the advantage? Will you be making gigantic prints which require minute detail? Will you be making significant crops out of the images? Do you demand the absolute very best that can be had (and that is, of course, a subjective judgment at best)? Otherwise, I think the 36mp model is overkill. Given that the a7R has some noted issues, if you do not already have one and insist on the 36mp model, I would wait a few months and see if Sony fixes the problems in its a7RII release.

For all of the same reasons, If you think you “need” full frame, I think most current Nikon users who are invested in decent or good glass could be really happy with the Nikon D610 and using the fabulous Nikkor glass?  Not sure if Canon has a like camera – but if they don’t, they will – seems to be a continuation of the “tastes great/less filling” argument between the “white hats” and the “black hats,” year in, year out.

“Full Frame” is a “fiction”

3.  Do You Really Need Full Frame?

What is “full frame,” anyway? It is a fiction. The “Full Frame” misnomer was created by DSLR users.  Long ago the SLR industry established a standard size of film for SLR cameras that had a diagonal dimension of 35mm (hence the 35mm SLR). But there have always been other formats, from sheet film in the back of a full view camera, to so-called “Medium Format,” (which had a couple different film rectangle sizes). All were rectangular (but lenses are round, leading comedian Stephen Wright, I believe, to wonder aloud why if lenses are round, why are photos rectangular? 🙂 ). But the lens size and length was generally designed as a function of the size of that rectangle of film.

In the early 2000’s, the manufacture of electronic sensors for cameras was a much more costly and limited process than it is today. In order to make a sensor that would perform in an SLR-like body using the lenses then available, the technology/cost matrix meant that an affordable DSLR would have the APS sized sensor (closer to the size of a standard U.S. postage stamp than to 35mm). This phenomena immediately created some issues with lens lineups. Because of the so-called “crop-factor,” the angle of view of lenses was decreased by about 1/2 (generally, multiply the 35mm-equivalent by 1.5). It varied slightly from camera to camera. But it immediately created a perceived issue for long time 35mm film shooters.  They began to wish for and even demand a sensor that was the 35mm rectangle their lenses were originally designed for, and began to refer to such a sensor as “full frame.” Eventually these sensors (probably already in the planning stages) were introduced and are generally referred to as “full frame.”  But try to convince a larger format camera user that 35mm is “full.” 🙂

At the same time, camera makers (and third party lens makers) began to manufacture lenses to the APS specification and in a sense, the “distinction” has become academic. It is no more “full frame” than any other sensor-size/lens combination which is properly designed for one another.  For those reasons, I am not sure the “full frame” reference is really a significant factor in one’s choice of camera.  More importantly, larger sensors might yield higher image quality.  That goes back to the discussion above about the “correct” number of megapixels.  See, I can use circular reasoning with the best of them.  🙂

When Nikon announced the enthusiast level “full frame” DSLR, the D700, I purchased one. By then, I had been used 2 iterations of the APS sensor (D100, D200) and had acquired some APS-designed Nikkor lenses. With the change “back” I had to completely re-think this lineup. I was never one who “yearned” for “full frame.” For the above reason, I never thought of it as a particular advantage or disadvantage. In fact, one advantage is that it is cheaper and easier to design smaller lenses for these smaller sensors. This is particularly notable in the mirrorless arena.  Of course, another advantage is that they will be smaller and lighter.

Sensor size is probably one area where “bigger is better,” at least in terms of quality. Bigger physical sensor size means relatively bigger photosites and as noted above, better, cleaner images (especially at the edges of light). That drove my move to the D700 100%. I wanted the best IQ I could “buy.” That motivated me to go to and stay with the Sony a7 also. On paper, I should achieve top-notch IQ with the “full frame” 24mp sensor.

Sensor Sizes Compared
Sensor Sizes Compared

But I have to question my own thinking here. Do I really need it? At least one of my “pro” friends tells me that if you want to sell traditional stock (read, Getty Images), you probably do. It is a matter of the minimum file sizes they will accept. I would bet 99.9% of the readers here are not full time professional photographers and do not plan to try to make (even part of) a living from stock sales. So again, do we need it? What are you using your images for? Again, the 99% majority are posting them on Facebook, or their own blogs and websites. Some are making books and cards and calendars and just snapshots for memories. Not many are making large (24 x 36 or larger) art-quality prints. and even then, the need for 36mp is probably limited.  I have a 24 x 36 art-quality print framed, matted and hanging in my office behind my desk that looks pretty darn good (if I do say so, myself) :-). It was taken, traveling in Venice, Italy, with the APS sensor, 16mp Sony NEX-6. When I travel, I always have to decide whether I am going to carry anything more than the NEX, a very small travel tripod, and an array of very small lenses to use with it, or the “bigger” outfit (for me, that is the 3 3/4 lb. Sony a7 setup these days). So, when size and weight become a serious consideration, so should these diminuitive APS mirrorless offerings.

The current version of the NEX-6 is the Sony a6000. It is intriguing: New “engine;” Improved a7 menu system (the NEX menu structure was mind-boggling – the a7 is somewhat better); 24 megapixel APS sensor (question about whether the same “spacing” issue of the photosites applies here? The photosites have to be smaller than those on the prior 16mp NEX6. A matter of tradeoff); Faster, better AF. Brighter viewfinder. If I were not invested already, this would probably be my entry-level purchase and just might suffice to be the only one. At only $450 a copy, you could buy 2 a6000 bodies for less than the price of one a7/a7II. You could carry them with different lenses attached. There is no 70-200 lens for this sensor/mount combination, but the 70-200 f4 mounts, and works well with it. There is a Sony-Zeiss rough equivalent 24-70 (the 16-70 f4). It has IS. The cost for this 2-lens combo and the a6000 would be $3,850. The weight would be under 3 1/2 lbs. (and 2 lbs. of it would be the 70-200!).

When size and weight become a serious consideration, so should these diminuitive cameras

I will watch with interest what competitors, Nikon, Canon, and Fuji do this year. I think Olympus is pretty much married to their 4/3 system and I think the smallish sensor size is just too much of a compromise. Nikon’s mirrorless array has been a non-starter for me, primarily because of their insistence on their own, proprietary sensor size/lens design. I don’t get it, Nikon. You already have APS sensors that are tried and true, and lenses designed for them. Sony has proven you can put them in a small package. Marketing, Nikon? I have no idea where Canon is in this – or why.

The next time I post here, Christmas, 2014, as well as some other holidays will have passed us by (not meaning to be insensitive or display my ignorance – but having been raised in the Christian tradition, all I know is Christmas) :-).  I want to say Merry Christmas to all my friends and readers out there and for lack of a better term, the “PC” “Happy Holidays” to all who may celebrate other holidays this time of year!

The Sony NEX 16-50 “E-mount” Zoom

Barn Copyright 2013  Andy Richards

Last week, I reviewed the Sony Nex-6 camera body. One of the interesting features of this line of Sony cameras is the large selection of third party lens adapters available, making it possible to mount almost any mount system lens.  While most of these lenses will use the camera’s auto focus (or any other “auto” features for that matter), they will work perfectly well in manual focus mode. There is some “quirkiness,” though. Neither the camera’s onboard information, nor the embedded EXIF information will give you the aperture value, the focal length or the shutter speed value. I used the manual metering system and the on-screen “real time” histogram feature to estimate exposure. And, it appears that on the lenses which do not have physical aperture settings, the camera will default to the smallest aperture and there does not appear to be any way to adjust that. On lenses with aperture rings, you will be able to set the aperture.  Sony does make an adapter for its own lenses (i.e., the A-mount series that mounts on its DSLR cameras) that will pass the autofocus and exposure information through to the camera body and vice versa.

I purchased the Rayqual adapter for Nikon “G” series lenses (these lenses do not have a physical f-stop selector ring, but are instead all chosen by one of the camera’s “command” dials). The G adapter will work with any existing compatible Nikon “F” mount lens (or any lens fitted to the Nikon F mount).  There are a number of manufactures that offer adapters, and reviews seem to suggest that quality of manufacture is all over the place.  The Rayqual was recommended to me by my pro friend and I thought it made sense to go with something known.  The guy at Cameraquest was very accomodating.

Of course, the camera’s “APS” sensor means you will have to apply the 1.5 field of view factor to the lens. But there are some very sharp, fully manual, older lenses out there (i.e., the venerable 50mm f1.8). I played around with a couple of my own Nikon lenses and found that in reasonable light conditions, focusing (either on the back LCD or in the viewfinder) is relatively easy.

My primary motivation for purchasing this Nex-6, though, was to find smaller, more convenient setup to use while traveling and while out walking around, that would give me image quality like I have grown to expect from my DSLR setups. The NEX has the promise of doing that, in my view. But using an adapter and manual older lenses may defeat that purpose. While they are fun to play around with, I don’t want to be doing that when I am on vacation in new places. I want to shoot and have reliably good quality results.

For that reason, the Sony E  SELP16-50 F3.5-5.6 PZ OSS zoom is a very attractive lens. The 35mm equivalent of approximately 24-75mm is a pretty useful range for “street” shooting and “walking around.” Of course, 28-300 would be nice (and they do offer that option), but it comes at the expense of size, weight, and … well, expense (the E-mount 18-200 is over $800). I don’t intend for this camera to replace my D800 DSLR. It is a significant upgrade replacement to my Canon G12, though and will undoubtedly get lots of use. As such I really wanted the 16-50 to be acceptable. It didn’t have to match up to the performance of my f2.8 Nikkors.


I am pleased to say, I am pretty impressed, given the challenges the lens faces. The lens, fully retracted, measures only 1 1/2 inches long (there is a serious typo in the dpreview literature – though it would be amazing to have a zoom of this range that measured only 3/16 inches 🙂 ). The overall depth of the Nex-6 with this lens attached is a mere 2 1/2 inches! The lens is image stabilized (OSS), with a minimum focus distance of just under 10 inches. Its minimum aperture (depending on zoomed length) is between f22 and f36. It is a very lightweight addition to an already comfortably light and small body.  The barn above, was shot at 50 (75) mm at f16.  You can see that at those specs, the lens produces a relatively sharp, edge to edge result.  But how does it do at wider apertures, and at other focal lengths?  You can see in the image below of the white house that, stopped down, the lens performs nicely at its wide end (note that this was distortion-corrected in ACR using its lens database).  For daylight images, I cannot think of a reason not to stop the lens down to its “middle” ranges (f8-11-16), unless trying to obtain a specific DOF result.

I will leave the technical specifications, like resolving power, distortion measurements, and other things to the technocrats and pixel peepers. My criteria was whether I was going to be able to bring home some “wall hangers,” using this lens. I think I can.

My non-scientific testing involved setting the camera up in my basement, mounted on a tripod using the same image, from a stationary position. I also used the IR remote to ensure no camera movement was involved. I am still trying to master the settings and particularly the AF technology on this little unit. To the best of my observation, the IR remote did not cause the camera to try to re-focus (which is a good thing).   However, as I glean more knowledge about the AF technology in this camera, I wonder if that is really what is happening.  From what I read, the default AF system in the camera works with “contrast detection” (as opposed to “phase detection” on most DSLR cameras).  What I am learning this means, is that the camera, when set to its AF setting, is constantly searching for a sharp exposure.  So, it may just be that in good light, the AF performance is just that good, and  and locked on when the remote triggered.

What I generally concluded was that there is little difference in sharpness from wide to small aperture and from short to long focal lengths. This is particularly true (as might be expected) in the center of the lens. But I am pleasantly surprised at the edge to edge performance. Granted, this combination is not going to be an architectural setup. Nor will it be up to the standards I generally expect from a “grand landscape” image shot with a “pro-specs” lens. But for its intended use, the results were very acceptably sharp and pleasant.  All images were at 100 ISO.

Other reviewers have noted that this lens suffers from significant distortion and some vignetting, particularly at the wide end.  The “before and after shots” here confirm this.  Both images were adjusted for contrast in my ACR raw image converter (Adobe Camera Raw), run through Dfine’s noise software and the default settings Pixel Genius’ “capture sharpening” engine.  They are otherwise uncorrected except that I applied the “lens correction” facility (again at its default settings) in ACR before opening it in Photoshop.  Some of the curvature can, of course, be attributed to the user.  A higher camera position would help here, if possible.  But you can see the pronounced curvature in the first image and the somewhat “tamer” curvature in the corrected version.  You can also see noticeable vignetting in all 4 corners of the first image and essentially no trace of it in the corrected image (no filters were used in this example, by the way, so this is the “bare” lens being demonstrated).  Sony is aware of this issue.  Again, I am not an engineer (and the world is a better place because of that 🙂 ) but it is my understanding that this is a design issue that cannot be overcome at this point (somebody will figure it out some day).  This is physically a very short lens for its zoom range, and also small, working on a larger sensor than many of these smaller lenses have used in the past.  To “combat” these issues, Sony has firmware in the camera that “corrects” for this.  For Nex users that are using one of the earlier models (Nex-3, 5 or 7), it is my understanding that it will be necessary to upgrade the firmware to take full advantage of this.  Caveat:  the Sony firmware correction will only work on jpg files.  For those of you shooting jpg (there is a 10-step program for you out there 🙂 ), I understand from what I have read, that this works very well indeed.  For the rest of us, some correction in post-processing will be necessary.  Adobe has done a great job of incorporating lens correction algorithms in their Light Room and ACR modules, including this lens.  I don’t have any familiarity with other raw converters or post-processing software, but it would not surprise me to find something there.  I consider the “corrected” image somewhat “normal” for this type of image, at the selected focal length of 16mm (24mm at 35mm-equivalent).

For the few who don’t already know this, the word actually comes from the Japanese, “boke,” and refers, in loose translation, to blur.  For photography purposes, it is usually referred to as the aesthetic quality of the out of focus areas rendered by the lens.  With regard to this particular lens, I can only really refer to the last 2 letters of the word in describing my reaction to the 16-50’s Bokeh:  “eh.”  :-).

Seriously, as I have said previously, it is a multi-purpose zoom in which Sony is trying to accomplish an awful lot of engineering, including a wide focal length range, reasonably wide apertures, and above all, very small footprint.  Given its modest price and versatility, I think they have done admirably well.  I think it would be unrealistic to expect it to stack up again virtually any prime lens and particularly the Zeiss glass or any of the Leica, Nikon, Cannon, Zuiko, Voightlander, or other “legacy” lenses that can be fitted via an adapter.  As part of my overall purchase, I picked up the pair of Sigma-manufactured e-mount f2.8 primes (19mm and 30mm).  When I get a chance to get in the field and do some real world testing, I hope to report on them. for now, here are two “test” examples.  Images are not very exciting, but given the time of year here, they are what I have to work with :-).  The first image is at the widest end of the lens, wide open.  The second is at the longest focal length, again, wide open.  I did not do any sharpening on these two images, so they are pretty much what you see is what you get (other than whatever PS did during the jpg conversion and resize, and I can say they looked pretty sharp on my screen as they came out of ACR).

I used the same default “capture sharpening” using Pixel Genius’s “Photokit Sharpener,” and identical contrast and local contrast adjustments in ACR on all the illustrated images.  I did not do any other sharpening.

While the light was not quite as nice on the final image, I wanted to include it to show that the lens is decently sharp at the wide setting and its wide-open aperture, too.  With appropriate “creative” sharpening in post-production, I can see that this lens will produce very acceptable images.

My Review of the Sony Nex-6

Barn Copyright 2013  Andy Richards
Copyright 2013 Andy Richards

I have been casually watching and reading about mirrorless, interchangeable lens camera systems since they first came out, playing around with the Nikon 1 and the Sony Nex-3 at my local big box store. Especially when you travel, or attend public events or places, it is hard not to wish for a system which is compact, sheds the bulk and weight, and is less conspicuous. But for me, main negative has been that the small sensors simply haven’t been able to generate the image quality that we now take for granted in modern DSLR cameras. In July of 2011, I reviewed the Canon G-12, a part of the Canon G-series cameras that have been used by some pro’s as backup cameras. I purchased the G12 couple years back, wanting a compact camera for those times when the DSLR just wasn’t convenient or wasn’t going to work in the situation. Following my review, I cruised the Caribbean for a week and carried only the G-12. I thought it performed well for normal daytime lighting situations. Unfortunately, much of the imagery I seek is in low and other challenging light conditions and I found the the small sensor performance in low light/high ISO conditions to be essentially unacceptable. I think the G-12 at the time it was introduced was probably the best sensor of its size.

It’s hard not to wish for a system which is compact, sheds the bulk and weight, and is less conspicuous

About a year ago, I learned that the Sony Nex series of cameras used the same APS-size sensor that many DSLR cameras use (indeed, I am told it is an updated and improved version of the very same sensor found in the estimable Nikon D7000 — in fact, what I am reading is that, as good a performer in the low light, noise handling area as the D7000 is, the NEX sensor is noticeably better!). That information piqued my interest in a less “casual” way. I began to research this camera and ask questions. I looked at the NEX-5 at a camera show last Fall. My biggest concern back then was the “investment” in body, add-on viewfinder, and lenses. The Nex-3 and Nex-5 (their first offerings), had no viewfinder. For me, that is a deal-killer (see below). If you want a good quality viewfinder, it is an expensive add-on option to the 3 and 5 models (a very impressive little viewfinder, I might add). It just seemed to me that the combination, for a second, “walkaround” camera was too much of an “investment” for this hobby photographer. The Nex-7 added a very impressive OLED (“organic light emitting diode) viewfinder, and some more conventional control dials. Both the Nex-5 and 7 have “touch screen LCD’s on the back. The Nex-7 has a 24 megapixel sensor and a couple other software bells and whistles than the 6. Otherwise, the 6 and 7 appear to be functionally identical.

The Nex-6 appears to have hit the “sweet spot” for serious shooters

There appear to be other alternatives, including the “micro 4/3” sensor, which is larger than the sensor found in the G-12 or the Nikon-1, and is reputed to be a “better” aspect ratio design for the smaller lenses that are made for these cameras.  My own research tells me that the APS sized sensor still has an edge over these smaller sensors.  There are also APS sensor mirrorless offerings from Fuji and Canon, Pentax, and Leica (and recently a wide angle, fixed lens model from Nikon).   Various factors ruled them out for me.   I will say that one disadvantage of the Sony system–at this point–is that they lag behind the others in variety of lens offerings.  But the Nex-6 has the very same sensor that Nikon puts in its D7000.  Together with ergonomics, price and some of the factors discussed below – this was the “deal-maker” for me.

The Nex-6 appears to have hit the “sweet spot” for serious shooters like me. Introduced with Sony’s newest “kit” lens, the 16-50 3.5 -5.6 in a very diminutive package, it has a 16 mp sensor, a retro-styled “mode dial” and dual control dials (top and back) much like those found on many current DSLR bodies. It has the same bright OLED viewfinder as the 7, and for the first time, a standard sized hot shoe (the 3,5, and 7 all have a Sony proprietary shoe that is not quite standard size). The controls appear logical and are nicely laid out. There are not so many of them that it is daunting to figure out how to fire up an use the camera immediately.  Importantly, I believe that with its ability to fit my Nikon lenses, it can now act as a backup to my D800 system in an emergency.  At the same time, I now have a camera that won’t sit in a bag and gather (expensive) dust while depreciating in value.

Here is my (non-exhaustive) roundup of the Nex-6’s most prominent features and some of my thoughts:

Available Documentation

In a word: Awful (this will most likely be my only really negative comment – and aside from the shipped documentation, is not a knock on the camera).

I am just asking that they cover the essential issues for the serious photographers to whom they clearly aimed this camera

The documentation that has shipped (both hard copy and the more modern PDF downloads from CD or the website) with almost any electronic for the last 20 years has been uniformly bad. That may be a good thing for the proliferation of writers and publishers that produce third party “missing manual” style books. But even the poorly written manuals that are in the box or available on the website usually give us at least the necessary information to understand how the basic functions work. The Nex documentation doesn’t—in my view—even do that. They have a plus-100 page downloadable manual and a similar “guide” (hard to tell any difference from my review). Neither of them logically explain anything more than the obvious (pointing out, e.g., where the power switch is; you know: the one that says both “on” and “off” on it? :-)), and then delving, in a superficial way, into ample coverage and explanation of all the “gee whiz” special modes and jpeg-only, features. I am not saying they shouldn’t explain those features (this is likely a camera that will appeal to and be purchased by a broad spectrum of users). I am just asking that they cover the essential issues for the serious photographers they clearly aimed this camera at.

The Nex line is touted as a highly sophisticated compact camera, suitable even, for professional use (and indeed, I know of one very talented and experienced professional who uses them daily). One must-have feature for any serious photographer—in my view—is the ability to capture in raw format. Yet the 2 downloadable pdf manuals are completely silent about which features and functions work and which do not work when shooting raw. And, there is a dearth of third party reading at this point.  One third-party book (admittedly an older book by David Busch and Alexander White, covering the Nex 3 and 5) is hit or miss on the subject. The title of Jerod Foster’s “Sony NEX-6: From Snapshots To Great Shots” should have tipped me off that this wasn’t really a book about the camera – but I downloaded the Kindle version anyway– A disappointment.  I am not saying there isn’t a place for these books.  But they are all written, in my view, as if the purchaser just purchased his first ever digital camera (maybe even first ever camera that was a step above his cell phone).  And in these “series” books written by the same author, they contain 85% generic information about how digital cameras work, exposure, f-stops, rudimentary comments about raw, how autofocus works, etc. (I just finished another one on the Nikon D800.  The author just cut and pasted 1000’s of words from his other so-called “camera-specific” books. I have read 3 of his books now and the sense of deja vu is “deafening”).  Seriously?  The D800 or the Nex-6 is the “first” camera a purchaser buys to “learn” how to photograph?  I have my doubts.  There is a book slated for publication in September. I will look forward to obtaining a copy to see where the authors go.   I am still looking for a third party a book explaining the functions and features of the Nex-6. Magic Lantern, where are you? (rant over :-))

General Ergonomics and Body

Several hackneyed sayings about “old dogs and new tricks” and “old habits and dying hard” come to mind here. But I am an “old-school” shooter (at least as old school as the 1970’s SLR shooters). I “grew up” with a TTL viewfinder, match-needle metering, manual focus lenses, and mechanical control dials on the camera body. The Nex-6 body was designed with that kind of “old school” in mind. The new top mode dial, (ala the similar controls on the later—venerable, but long-in-the-tooth—Canon G-series and the Nikon D7000 series), is a nice “comfort food” feature. It controls the so-called shooting mode (PASM, etc.), which are all menu functions on the other Nex cameras. Directly underneath it (mounted on the same axis and slightly larger in diameter) is a control dial. There is another control dial on the back. This is a lot like my Nikon layout (sans the front control dial), and thus familiar. I like that.

The Nex-6 body was designed with the “old school” shooter in mind

This camera, much like the Canon G-series did, feels comfortable in my hand. The right-hand grip is nice and the body has an almost leather texture. While some with larger hands may find the space between grip and lens tight, it is a tradeoff for the compact size of the camera that I think is worth while. The camera is just 2 1/2 inches deep from viewfinder to lens cap (with the 16-50 attached), 5 inches wide from d-ring to d-ring, and 2 3/4 inches high from the base to the top of the mode dial on the top right. It has a nice “heft” without being an anchor. The top control dial is easily reached and manipulated by the right thumb, as is the rear dial. This means with a little acclimation, you can make essential settings without taking your eye from the viewfinder.

Most compact cameras have been, it seems to me, designed toward the P&S consumer market. The early Nex series is certainly no exception. The 3 and 5 are completely menu driven and totally reliant on the rear LCD screen. An electronic viewfinder (EVF) is available as an (expensive) add on. The “flagship” 7 has the same built-in EVF that is now on the 6 and has two unlabeled control wheels on top of the body (in practice I am told it doesn’t take log to acclimate to their functions).

The Sony OLED EVF takes some getting used to, but I quickly grew to like it


I have shot with a viewfinder for 35 years. While there may be something to be said for getting out of the comfort zone, in this case, the viewfinder lets me isolate and “see” my image. So for me on all my cameras, lack of a viewfinder has been a deal killer. The Sony OLED EVF takes some getting used to, but I quickly grew to like it. Unlike the traditional “rangefinder” cameras that had a mechanically coupled, but compeletly separate viewfinder, the EVF is, in essence, a “live view” TTL finder.  No parallax issues and “what you see is what you get.”  I am not sure what the coverage is, but I am reasonably sure it is 100%.  The EVF is very bright and because it is not a traditional “optical”  TTL finder, it can have some unique and useful behavior. As you rotate the command dials and change either the aperture or the shutter speed, the image in the viewfinder actually grows brighter or dimmer as the exposure solution is changed!  You “see” the image come into an approximation of correct exposure. Very cool.

Another nice feature (becoming more the norm – the tech just keeps getting “smarter”) is the automatic setting that senses when you bring your eye up to the viewfinder and turns it on and the back LCD off. You can override this behavior and even turn the LCD off completely to save on battery drain.

You can also set up the viewfinder to display the important information, including a horizon level indicator and, if you wish, a real-time histogram. And, of course the viewfinder—like my DSLR—shows essential information, like exposure, shutter speed and f-stop settings.  I have set the horizon level indicator in my viewfinder and it–unlike the ones one the back LCD (my G12 had it), actually works pretty well in handheld shooting.

The potential for lens selection and use with this camera appears to have little limitation

Lens Selection

Here is where the Nex series gets interesting. The potential for lens selection and use with this camera appears to have little limitation. In order to have all the offered metering functions, auto-focus, and some of the added features, you will, of course, need to have lenses with the proprietary Sony e-mount (Sony also offers an adaptor for their DSLR-mount lenses that will allow essentially all the functions). Sony currently offers 13 different e-mount lenses (I have oft-noted that these equipment reviews are my empirical and practical observations and are anything but technical. There is an abundance of commentary on the relative sharpness and other characteristics of these lenses and I’ll leave you to your own research on that topic). My Nex-6 came with the “kit” SELP1650, 16-50 f3.6 – 6.5 zoom.

Sony 16-50 “kit” lens:    It’s all a matter of perspective (pun intended). Against my Nikkor 24-70 f2.8, the 18-55 lens that has shipped as the “kit” lens on the prior Nex-series bodies is small and light. But for a compact camera, it’s still a bit chunky and the heft is noticeable. The new 16-50 is downright diminutive. About a third the length of the 18-55, it is also much lighter, making the Nex a (barely) “pocketable” camera (think cargo or jacket pocket – not jeans pocket).

Critics say it is not a “sharp” lens (those same critics often also criticize the 18-55). Lets face it. Its a relatively wide range, variable aperure zoom, at a mid-price range. There are going to be some compromises. I don’t have an 18-55 copy, so I cannot do comparisons. But my results on the 16-50 seem pretty good to me.  The barn at the beginning of this post was taken handheld, all manual (except for AF) with specs of f16 and 1/100 second.  But, I wanted to see how it would perform at wider apertures, so I did some of my own unscientific tests.  My conclusions are that as a practical matter, the lens performs very well at almost its whole range of apertures in terms of sharpness for general photography.  I use ACR in Photoshop and routinely correct for lens aberations, using their built in database, which seems to do very well.  I will cover this lens in my next blog, as this one is already too long.

The filter size for this newer lens is an odd, 40.5mm. The only filter I generally use is a polarizer. They are surprisingly expensive for this size. I did learn in my research that because of the way AF is accomplished in these cameras, a circular polarizer is not necessary. I was able to find a B&W linear polarizing filter for a reasonable price.

Non-Sony Lenses: Here is the exciting part. For a relatively small cost, you can buy a third party adapter and use a huge selection of lenses from virtually any lens manufacturer. This is all done fully manual, but the bright EVF makes focusing easy.  One challenge appears to be that my newer Nikon lenses which do not have manual aperture rings, will not allow me to choose my aperture.  For the most part, in my likely emergency backup scenario, I will be looking for maximum DOF throughout, which is a good think, because the NEX appears to choose the smallest aperture, and require you to vary the shutter speed.  Wind, of course, may well be a concern.  When the series first came out the native “e-mount” lens selection was very small, including only 2 lenses. The Sony selection has grown to several and is likely to continue to grow. And even better, some other manufacturers are now making lenses in the e-mount, including Sigma, and excitingly, Zeiss. It can only get better.

Function button

At first, I was perplexed by this button. It doesn’t behave at all like I expected it to. On my Nikon DSLR bodies, there is a function button that you can assign certain features to. When you press it, it performs that single task (e.g., on mine, I have it shift from averaging type metering to spot metering. The documentation, once again, is hopelessly unclear. So, it took me a while to figure out that on the Sony Nex, the Function Button really acts more like a “quick menu” submenu button, bringing up a short list of settings changes.  Unfortunately, customization here appears limited.  I cannot have the “quick menu” list the functions I want it to.  I have choose from their options.  Maybe a firmware update, Sony?

Other manufacturers are now making lenses in the e-mount…It can only get better

Rear LCD Screen

The generous 3 inch by 1 3/4 inch rear LCD screen is bright and clear. It articulates some (not as much as on the 3 and 5, because the addition of the viewfinder interferes with that). But it does pull slightly away from the body and tilts to a horizontal position for those who use it. I can see its usefulness in my own shooting style in those rare occasions where I might want to hold the camera out away from me.

The 5 and 7 have touchscreen capability. That is a useful feature, especially when using the features that might require inputting information into the camera. This would be particularly true if using some of the camera’s WiFi features.

The Nex-6’s WiFi capability should be a big deal, but for now, it appears to be “DOA”

My only concern is that I am one of those guys who has a near “reverence” for the beauty and maintenance of my equipment. It is rare for me to have a scratch, ding or other imperfection on any of my gear (no matter how old), and that big, exposed screen makes me nervous. I have added a screen protector (but I generally hate the things as they are a pain to apply and rarely look good).

Battery Life

This is a mildly “disappointing” area.  Battery life could be better.  There are a lot of electronics going to suck life from the small battery.  The AF on these cameras is contrast-detect oriented and by their nature, they are pretty much constantly “searching” for focus when AF is on.  I like to use the “review” features on the back of the camera, and tend to leave them on at longer intervals than is necessarily recommended.  The bright EVF viewfinder no doubt uses some energy from the battery.  I am philosophical about this one.  A spare battery and and external charger (the camera does not ship with an external charger, btw), is relatively cheaply acquired.


You may wonder why this is relegated to the bottom and I don’t give it much coverage. The Nex-6 is the first Nex body to ship with integrated WiFi capability. This should be a big deal! But for now, it appears to be DOA. The reason is that its implementation apparently is rivaled only by the Sony Documentation I bashed above. I still haven’t tried it, as it sounds like those who have, universally say it is wonky, doesn’t work well and is generally a PIA. I guess the good thing is that the capability is built in and one can only hope the subsequent software updates will make this pretty cool feature more workable and useful. I was pretty excited when I first read that I could use my iPhone as a remote shutter release and monitor!  I have enabled my Nex-6 with my iPhone 5, and have used it in my house as a remote.  Its pretty darn cool!  Once you figure out how to get the camera to “join” the network (it takes a master programmer – don’t expect any intelligible help from any of the available documention–you use a localWiFi connection, but once the camera logs on, it then names itself as a network and that is what you tell the iPhone to join), you will not only be able to use the phone as a remote shutter release, but the phone’s monitor becomes a live view monitor for the camera!  It was fun to play with and with my iPhone armed with a pdf manual, TPE, and GPS and Mapping software, you will have a pretty good accessory to the camera.  Lets hope they get this fixed—and right.

Things I would like to see added in new firmware or design:

Dedicated AF button: I use the back AF button on my DSLR bodies most of the time when doing landscape shooting (especially from a tripod). I turn off the AF activation from the shutter button. On the Nex-6, it seems like you could program it so when video is turned off, you could assign that function to the video button.

Custom Shooter Banks: the D800 (and other Nikon bodies) allow you to set up a couple (4 on the 800) custom shooter banks. I currently use only 2, a Landscape and an Action bank, but that would be a useful feature.

More Customization of the “Function” Button:  As I mentioned, I would like to be able to populate its short list with the functions I, in my own discretion, access the most

Tentative Conclusions:

Let me say that I love this camera–so far.  I think positives solidly outweigh the negatives.  It appears that it will be the answer to my desire for something more “usable” in conditions where setting up the “big guns” is simply not practical or convenient.  And, I think it really has some crossover potential, so that I will feel that I can achieve photographic goals with it even though I do not have immediate access to my D800.

I don’t have any illusions that it will become a “replacement” for my D800.  They are different tools for different purposes.  But it would not surprise me to see the Nex get more use on a regular basis than the D800.  My good friend, mentor, and pro photographer, Ray Laskowitz, made a very interesting, and I think apt observation.  He views the D800 the new “medium format,” in the sense that it creates such a massive megapixel image size (of course, the handling is the same as it always has been for an SLR camera).  The newer compact, APS sized sensors in these cameras like the Nex are making them essentially a more portable DSLR.   And rumors abound that there will be a (so-called) “full-frame” sensor compact in the not too distant future.  I don’t know whether I’ll consider that overkill or not.  Technology marches on.  The Nex is surely electronically equivalent to today’s DSLR models.  Imagery will, over time, tell.  I am looking forward to using it more and hopefully, from time to time, reporting back here.

Next week:  The included Sony 15-50 zoom lens.  Stay tuned …………………………..
