That's not true; HCI, ergonomics and industrial design are well-studied disciplines. Putting two buttons too close to each other is bad design because one might be accidentally pressed when aiming for the other. Not having positive feedback is bad design since it reduces affordance. Changing control placement on different models is bad because it forces the user to re-learn. And so on.
I have summarised
Ten Interface Design Principles on my blog (and a reader added an eleventh I thoughtlessly omitted).

Actually I am happy to have high-quality video on my SLR since this means I don't need to buy another device. Plus I can leverage my lens investment. But the truth remains that the use and desired features of a video camera are simply not the same as that of a still camera. In the former you need pull focus in the latter not. In the former you need a large monitor, in the latter not. The former needs to print a high bit-rate stream of relatively low res images while the latter needs to print at a lower rate higher res images -- which is why DSLR sensors overheat... they are being shoe-horned into being used for the wrong purpose. And so on.
In short, a DSLR can make a reasonable video camera, which in fact they already do. But to make further improvements means turning them into a different device... a video camera. And apparently we already have those. In fact Panasonic and Sony have their micro four-thirds cameras to market, blowing away what was previously possible and allowing any lens from any manufacturer to be freely used.
Pentax cannot compete with anything like that. So instead they'll just keep adding glossy features for bean counters and magazine reviewers. I totally understand this but am not impressed by it.

Or better yet, Metz. Weather-sealing, rubber guards and two soft buttons would improve the 58 AF-2 nicely.
