A growing cult.
Read Douglas Brown's experience with the A700 at Luminous Landscape.
Here's an extract.
"It's tough, ergonomically well designed, intuitive to use (I still
haven't read the manual and yet managed to instantly come to grips
with and even customise a lot of the camera's features)"
Ergonomics is a fickle thing; what one considers 'ergonomic' will
always be influenced by previous learning. So a pro with many years
of experience may well prefer old camera designs, but if he were
learning photography for the first time today, he may well find the
new designs easier to come to grips with.
That's "habitability" of the user interface. Only one small aspect of ergonomics. Other aspects include control effort, operation speed to a habituated user, potential for strain injuries...
Although user interface design is a big part of what I do, I am not a full time HFE (human factors engineer). I have had the privilege of working with some of the best, like Diane Gourd, who also worked on CAESER, and I learned a bit about reach zones, joint motions, effort measurement, etc.
I've applied some of this to assistive technology, both ergonomic modifications of instruments for injured or challenged flutists, and some pretty radical work on cameras for challenged photographers. Placed subcu probes and monitored motions on an EMG to locate the lowest strain control placements. I used to have a nice four channel EMG.
There's also wonderful CAD software that can do ergonomic simulations and contains massive anthropometric databases, any percentile, any gender or age range, any ethnic group. You bet the camera manufacturers have access to these kind of tools.
The biggest difficulty user interface designers face is "folk wisdom" that is often nothing of the sort. For example, did you see what anastigmat spewed out about the poor ergonomics of having essentially identical buttons. That's the kind of tripe you get from someone whose ergonomics education consists of reading brochures on audiophile car tuners.
Buttons designed to be worked by the same fingers are the most ergonomic when they are the same size and shape. There are actual tables and databases for the different motions of each finger at the different anthropomorphic ranges. If the work task permits the arms and hands to be moved, allowing the fingers to be located for an optimal motion, then linear placement also makes sense. Look at a piano keyboard, 88 keys, linear, essentially identical (the black keys being placed according to acoustic necessity)
That said, I don't quite see what Joseph S. Wiz. is referring to when
he says the A700 'have designs that place controls where they had to
be 20 years ago'.
My apologies, I had not noticed that A700 was the first Sony do do away with the shutter knob that is placed where the link shaft to a Copal Square shutter would be. This has been a pet peeve of mine about the Minolta cult for many years, touting that disaster as "ergonomic". They're down to just one major control, the front command dial, being really screwed up, and it's not a 20 year old error, it's just weird. I can think of no reason for their front command dial placement, it causes unnecessary pronation of the right first finger.
On the other hand, he isn't exactly known to be a
Canon fan when it comes to ergonomics.
Canon has been wasting real estate on that big, round, purposeless dial for decades. When they finally did put four way controls on cameras, dodging the dial meant awkward placement for something very critical. They've consistently made grips that are sized for hands much smaller than global 50th percentile, as if they were designing only for the Japanese market.
I've always thought it would be fun to round up high line and midline cameras from all the major players, a statistically significant number of photographers, and an EMG, and measure which cameras really do have the best ergonomics.
I know when we did it with one Leica shooter who kept going on about the shutter position on an R9/DMR vs. the modern control dials like Nikon and Canon use, he was pretty shocked to find it took about half as much effort to work a Nikon D2X than the "ergonomic" Leica.
