I shoot a Pentax DSLR and, for the last few months, an E-P2. I shoot almost exclusively in Aperture-priority mode with both cameras. On a recent trip I found myself frustrated with how many "spins" I had to give the thumb wheel on the Oly to change aperture (not a stop or two, but going from 1.7 to 5.6, for example). Has anyone ever heard of a digital camera that allows the user to program in the f-stops he wants the camera to scroll through when turning the aperture scroll wheel? For example, setting only full stops so you can scroll through faster, or even only two stops, like wide open and f8 for quickly switching between shallow DOF and general street shooting. Just a thought, and something I haven't heard of before. Has anybody else?
