I'm not convinced about that.

I was using those dials all the time as a 16 year old learning to use a camera. It's really easy - especially when you can set one of them to auto and just control the one you care about - plus so quick when they're on a dial.

But I can believe no one wants to do it now, it's amazing how much a bit of tactile feedback can make a task 100X easier, and something you can do instinctively.

Tactile feedback and consistent UIs are great and a common feature (if not a defining one). I've got a Pentax dSLR -- it's got an excellent UI (better than canon's, imo) and their manual tweak focus adjustment & focus hold system does just work very well. It also has an excellent set of manual controls. A pity that nobody else has heard of them...

> Most "pro-sumers" wouldn't bother to adjust what the auto-focus calculates anyway.

I think that is the 'sumers. The prosumer gear is for people who actually want to play with all that stuff, but don't want to pay $10k for a pro body and lenses.
