Ah, that's the source of the confusion. Yes, Pentax's entry-level bodies add an extra button that you have to hold down so the control dial knows what it's changing when you use it. I was talking about bodies which do not require you to do that: when you're in manual mode, the dial (which has to exist anyway) is the only thing you need to use to change apertures. For the entry-level bodies I agree with you that it's another button added, though people who value simple user interfaces would hardly be using an entry-level AF body on manual mode. chris
