It's Monday morning and life is as crazy as ever around the Visual Science Lab compound.



it's Monday morning and Studio Dog is NOT HAPPY!

Studio Dog and I woke up to a 7 a.m. doorbell. It was someone from the construction company we hired. They were ready to start working on our roof and needed me to move the cars out of the driveway. Studio Dog did her territorial barking and then she and Belinda and I went out for our morning walk through the neighborhood. I think she assumed that all the noisy people in her yard would be gone by the time we got back...

Belinda went off to work at the advertising agency and studio dog and I went out to the studio to get the day started. Of course, if you've had your roof replaced you probably know that it's a loud process. People are walking all over your roof and ripping up old shingles, dropping bundles of new shingles into place and making little earthquakes here and there. I understand the process but Studio Dog is mystified, terrified and a bit miffed. Mostly terrified by ever new acoustic affront. 

There's some construction to be done and then there's more painting and we'll even have some screens replaced on the porch but all in all the heavy stuff shouldn't last more than two or three days. Unlike our neighbor's McMansion project which is now about to enter its third year of stop and go construction.

Studio Dog is currently sitting under my desk as I type. Occasionally she reaches over and pokes me on the calf with her paw as if to say, "WTF?" Progress moves ever onward.

The Olympus Wrap-Up. I spent a lot of time last month with two different systems in my hands. Nikon and Olympus. Both have their charms and it was instructive for me to work back and forth with both systems in tightly scheduled shoots. When I shot portraits with the Nikon system I found myself almost always reaching for the D750 over the D810. The camera is smaller and lighter and a bit simpler, and I trust its focusing system maybe a little more than the system in the D810 when it comes to using longer lenses near wide open. I don't trust either enough to manually focus important work without resorting to live view and punching in (increasing magnification) to confirm sharp focus. I understand that the D750 and D810, when used correctly, give me files that have more detail and perhaps better dynamic range than the Olympus EM-5.2 but I think that the qualitative differences are more or less academics, for the most part. 

While the specifications would lead one to believe that the differences should be obvious to anyone with good eyes the real answers are far more nuanced and have to do with the way you light, the size you use the images and what part of the range of aesthetics is important to you. To my mind there are few reasons for me to shoot bigger formats other than the times when I want the different look (in terms of how quickly focus falls off) of the larger format sensor combined with fast, medium telephoto lenses, and times when clients need highly detailed files that can be enlarged beyond the scope of cameras with less resolution. The arguments about dynamic range and high ISO performance seem to be of less importance in my work. I light for dynamic range instead of solely depending on the camera and I've found few instances where the dynamic range of the Olympus camera is a challenge compared to the Nikon cameras.

There are times when I like the extra margin of quality I can get shooting the bigger sensors in low light but those times are something like once a month; usually when shooting at the theatre. It's something I would notice and you would notice but when the image is shrunken down to quickly sharable, web size the advantages seem to shrink with the file size. The reality, and I don't know why this isn't talked about more, is that both the Olympus cameras and Nikon cameras are using the same basic Sony technology sensors. My thought (and I may be wrong) is that the Olympus sensor is the same, exact science but just a smaller chunk of the overall package. With that logic it would stand to reason that if you used both sensors to make prints that equalled the maximum native resolution of the smaller sensor (equalizing by focal length) that the resulting images would be technically identical before undergoing whatever custom processing each maker then overlays. That would make the sensors equal except for overall size (geometry). 

While we've been on a junkie-like spree in the pursuit of high ISO performance and high resolution it seems more logical that most people making photographs would be more interested in how well the color works and how nice the tonality of the files works TO THE EYE of the audience. In this regard the metrics of camera superiority are also not so easily defined. 

If I shoot both cameras in the Raw file mode I can pretty much equalize the look of the two cameras in post production. The Olympus starts out to be easier and is nicer to use directly from the camera. The Nikon files are in no way bad, they just don't look as organic and polished as the Olympus files. Regardless of the idea that they possess more "groovy, magic" stuff and numbers, the files from Nikon cameras seem more mechanical and machine-like. In many regards these differences boil down to differences in taste more so than acute differences in measurably technical parameters. 

There are power users and there are pleasure users of cameras. Sometimes the Venn circles cross a bit. But there's no substitute for using cameras day in and day out to understand what is important to you (for you, NOT that guy who shoots football or the woman who only shoots weddings and babies...) in the operation and output of a camera. 

Many years ago, when I first started using EVFs it was a happy epiphany for me. The EVF is such a better feedback loop than the traditional finder coupled with an LCD screen on the back of a camera. While a Nikon camera will outperform an EVF camera for continuous AF and AF tracking, and the OVF is pretty eye candy, from a real world usability point of view the EVF smashes the OVF every time. It's what makes the Olympus cameras a significant tool for me. I found, time and time again, in conferences, when shooting theatre, and in day to day situations in which I am shooting available light portraits, that the contemporaneous and constant feedback of the image in the finder, complete with an indication of how the color and exposure will turn out in post production just trumps the crap out of most of the advantages of the larger, mirrored cameras.

At this juncture I generally start to get reader comments about how when shooting tethered none of these advantages are exclusive. Well, guess what? I don't shoot tethered. Not my style and not something most people do at events, etc. You shoot tethered? Congratulations, shoot with any camera you like.  We also get the sports guys coming in to scream about continuous AF focus tracking with lock-on at 10 fps. Well, congratulations! I guess you already know which camera works for those very specific needs. I won't talk about BIF shooters because I just don't get it. And that's okay. 

Everyone from the experts on DPReview to Thom Hogan and Ming Thien think they are experts when it comes to explaining to camera makers what to do to reverse the slide in sales of medium to high end cameras. Distressingly to me they tend to concentrate on stuff like Wi-Fi (the Devil's camera feature), or a different lens line up, or moving some buttons around. The hard core reality from my point of view is simple = get rid of the traditional OVF and put EVFs in all but the specialty cameras. 

Once people had a taste for automatic transmissions you didn't see a ground swell of support for maintaining or bringing back manual transmissions (except for Europeans trying to squeeze a tiny bit more performance out of each liter of gas/petrol). Most of us are thrilled that we now have on hand free to hold our cup of coffee while we drive. We end up at the same locations and at the same time but we've had one less thing to worry about. 

It's a flawed analogy and I know it but it works for part of the argument. Once most photographers have used a system with a great EVF (Panasonic GH4, Olympus EM-1, EM5.2, Sony A7Rii, Fuji XT-1 and even the Sony RX 10ii and the Panasonic Fz1000) and have experienced the instantaneous, eye level feedback while shoot, they never willingly want to go back. Ever. It's just a better way to work. Much better. And it's a plus for camera makers who can eliminate some of the most expensive and fault-prone parts of their cameras. That includes the silvered prism, the moving mirror (the system of which also affects the focusing accuracy of cameras) and the attendant linkages. I know that if given a choice, with all other parameters being equal, I would always choose the EVF. 

So, if I were presumptuous enough to give Nikon (for example) some marketing advice to move their pro and prosumer markets into the second decade of the 21st century it would be to make the same basic cameras but to eliminate the moving parts and make the jump to state of the art EVFs with all their attendant advantages. 

I keep the big Nikons around and use them for stylized portraits with very narrow depth of field. I could get a similar effect with the fastest m4:3 lenses but it's not exactly the same. And having the depth of field "ramping" argument at hand it makes sense to also keep the bigger, full frame cameras for those high paying clients who are still interested in the absolute highest level of quality as it relates to the resolution and, well, resolution. It's nice that the D810 is soon sharp and so detailed. It's nice to be able to offer those attributes to clients. But when you know that giant print size, 4-C printing for magazine double trucks and things of that nature are off the table the easy, joy and increased agility of the smaller cameras is addictive. 

I split last month almost evenly between the two opposite style systems. I came away with good images from both. But when I finished up with everything I still couldn't decide which way was the single way forward. I still found myself wanting both sets of cameras to use in the appropriate fashions. But one thing I did discover was the all the boats have been lifted  in the camera industry. By that I mean it was easy to shoot really good images with the smaller sensor cameras and long lenses and still get remarkable images at ISO 1600-3200. 

It made me start to reconsider something I toyed with several years ago and that is the category of cameras with one inch sensors. I had the first generation of Nikon 1 cameras and really liked them. The lens line was far too sparse then and the 10 megapixel sensor not quite competitive enough for most assignments. I also had the Sony RX10 camera with its one inch sensor and it was quite good. With 20 megapixels it could do really good work and the color and features were nice. Mine developed a mechanical issue over time and I returned it to my dealer. 

Now, after having done a show that benefited from the long reach of the 50-200mm on the EM-5.2 my attention has turned to one of the one inch cameras that has always interested me but never got me excited enough to click on the "buy" button. That would be the Panasonic Fz-1000. Its price has dropped to $750 from most dealers and it's now low enough for me to take a more focused look. It's got the reach that the 50-200mm afforded me, a really good sensor (same as the original RX10) and the bonus is a pretty well implemented range of video features, including 4K. 

I think mirrorless cameras got off to a slow start for a number of reasons. The EVFs weren't nearly as good in the early years. The first target markets seemed to be families and amateurs. There were a lot of good, fast lenses available (and there are still a few dead spots between the Olympus and Panasonic lines = where is a good, fast 24-120mm equivalent???). But things have changed. The GH4 is a thoroughly professional camera as is the EM-1 and the EM5.2. The last prejudice is about files size but I think all but the slowest photographers have figured out that we've plateau'ed into a sweet spot in the 16-24 megapixel space and that the differences between the contenders are marginal at best. Especially when used at the sizes most images are  used. 

My long month of going back and forth has convinced me that I still need both systems, but it's also convinced me that the addition of a few faster lenses might make up the difference handily. There's an evolution happening in cameras and software. Not everything has to be done the old way. But it's an individual choice. I can hardly wait to see what Olympus and Panasonic come out with next. 

I'll keep you posted on the Panasonic fZ-1000 but for now I better go see what's got Studio Dog vexed now. Poor girl.

I basically took the month of September off from swimming. My work schedule interfered with my exercise. I ended up having to grab solo swims where possible. I am back to the daily 
swim schedule and the two long weekend workouts just kicked my ass this week
I was in bed by 10pm last night feeling hammered. I'm still sore today. 
The high price of staying in shape....

Kirk,

This is the kind of gear talk I like. As Ctein has mentioned a time or two over at TOP "data trumps theory." I haven't looked at any of the newer EVFs lately, but the one in my Sony R-1 maybe old and slow but it is very cool. One criticism I have of some of the mirror free cameras is esthetic (and false advertising). I really dislike seeing prism humps that are not needed. I find Olympus cameras to be the worst and that is from someone who still has and likes the looks of the OM-1 that I bought new in the '80s. Go figure. I sometimes wonder what cameras would have looked like if Daguerre, NiƩpce, Fox Talbot and their contemporaries had been presented with current sensors and batteries, etc. And how would we be talking about color and monochrome photography with sensors that natively produce images in color? (I woke up at 3:30 last night and never got back to sleep. Does it show?)

It's always good to see pictures of studio dog (I hope she comes through the construction ok) but the picture of the pool calls out to me. Now to get that shoulder loosened up so I can swim in a straight line instead of a large circle.

My sympathy to Studio Dog. The roofers should be attacking my house as soon as this rainy spell passes. My middle-aged tom cat is not going to enjoy it.

Other than that, I'm with you on the cameras. I have used mostly m4/3 since the G1 came out in 2008. A few months back I popped for a used D800. It makes a sweet image, but after years with an EVF the SLR design seems clunky. And, echoing something you said, I see the difference but none of my clients or viewers seem to notice. If the audience doesn't see it does it really matter? Too deep for me.

And where the hell is Olympus/Panasonic on a 24-120 equivalent? Olympus had such success with their 14-54 (which I still use on adapter) and then the 12-60 -- how can they not see the market?

Exactly!

Wow! Roofing is loud. Really loud. But it's a good thing we started on this as we caught some wood rot early on and it's being remediated. Plus, who doesn't want sparkling, new shingles?

I agree with your conclusion that the files we get from today's cameras are more than adequate for most purposes. When I see how sharp, detailed and clean said files are, I think "these images compare favourably with the large format photos of yesterday." Your shots of "Evita" done with a smaller sensor(in my humble opinion)look as good as a 4" X 5" or 2"X 2" colour slide film images did back in the day. And given the lighting challenges you mentioned, shooting colour slide film would be nigh on impossible. The differences between the various formats, for me is negligible at this juncture.

Shingles? Schmingles! Can't you buy terracotta tiles or slates that don't need replacing for 100s of years?(Then again there's always thatch.)

Such a cute dog!

My view is that so-called image quality "sufficiency" should be judged by whether or not the end results are meeting or exceeding expectations. Many times projects are ephemeral and don't need to be "future-proof."

Is a given camera/lens/tripod/lighting combo future-proof? Here's how to find out. Find someone with a 5k Imac. Take a look at the images from your gear. Do they look good? If so, they are probably "future-proof" for at least a few years. Many cellphones produce images that are NOT "future-proof," but can still be very valuable for documenting family life.

For the first time in a couple of years I used my Canon DSLR and OM-D EM-1 last weekend (the former because I needed my ultra wide and haven't bought the new 7-14 for the OM-D)
A couple of observations:

Canon
- I can't believe I used to lug the Canon with me just about everywhere it weighs so much.
- Where is the focus peaking and ability to ensure focus is nailed without resorting to compensating with aperture and chimping :)

Olympus
- Love the Livetime/LiveBulb feature - seeing a long exposure develop like in a darkroom still amazes me - it made long exposures with light painting a breeze compared with DSLRs
- Love being able to get instant confirmation of exposure and focus without moving the camera from my eye
- Using my phone to control the camera used up my phone battery fare faster than my camer battery - at least I can swap out the camera battery :)

Both
End result almost impossible to distinguish which camera was used (unless you knew I don't have a ultra wide for the OM-D)
