So I was just dreaming about random designs, and I thought - what if aps-c bodies got a third e-dial? Not like the K-1, of course, there isn't space, especially on the consumer bodies. But what about one that is like the control wheel of a Canon camera, right behind the shutter button? Then it could be programmed via menu to control something, for example, ISO - I, if not anyone else, would find that useful. But then where would the green button and exposure comp button go?
Just some random thoughts
It'd be pretty neat if all pentax bodies could boast three e-dials. Although i'm not certain its all that useful for everyone. But then gain, many people argue that two dials aren't useful, they're happy with doing AE+scroll wheel...
