touchscreen??? on a pro level dslr? no no no!
Phase One has touchscreen on their new IQ1xx medium format camera backs, and the backs are supposed to work in rough conditions. Not sure how well the touchscreen works though.
just because Phase One does it doesn't mean it's a good idea. I shoot plenty of places that I'd really rather not take my gloves off. touchscreens don't work through gloves (unless you get one of those with the metal contacts, but those are rarely insulative gloves). bad idea.
Yeah, it just means that pro-level equipment already does it. The phase one backs can be operated both using the touch screen *and* using four large buttons. The glove-operated mode would be using the buttons. The touch screen is faster to work with when you want to zoom in a specific area of a picture for example, but you can do the same using the buttons (if I understood the description correctly, haven't tried them myself so I'm not 100% sure how the ui works).
I agree that a touchscreen-only interface is a bad idea (even if it would work with gloves, fingers get too thick with gloves on), but think that a combined version could be nice. Overall, I think the live view and histogram etc can be much improved. For tripod-mounted landscape / architecture shoots I use live view almost 100%, and needing to scroll around with buttons and zoom in to verify focus does feel a bit awkward. It seems like the latest medium format backs have come a bit farther in this respect.
