They're only this way because that's how most of us use them. There's no reason why we can't set exp. comp. at -1 for the whole roll if we want to push film, or why we can't set the ISO at a different speed for one or two shots. > Setting the aperture with a conrol on the body, or on the lens > is still just setting the aperture. And using ISO overrides and exp. comp. are both just ways of shifting your exposure until you turn them off. > > Have you used a Z1-p?

What you said was "you can only use > one at a time" And how does that contradict what I just said? You can only use one method of selecting aperture at a time. When you're using the lens method, the body method is automatically disabled with cameras like the Z1-p (not with entry-level models, though). When you're using the body method, the lens has to be locked on "A" and so the lens method is disabled. If you unlock the lens to switch apertures, the body method automatically becomes unavailable, as it requires the lens to be set to "A". > > > Pardon me?

Nope, that's where you're wrong. The entry-level bodies work the way you think, but I'm talking about the better ones, like the Z1-p. When you're shooting in manual mode on these cameras, the wheel changes aperture by itself. You spin the dial, the aperture changes. No other buttons or dials are necessary. chris
