Originally posted by pres589 Not counting for the few focus-by-wire Pentax lenses, all (both?) of which are crop-only anyway, as long as it has an aperture lever a camera like the Super Program can control the aperture and provide a lens/camera combination that is usable (meaning, not shot only wide open or only stopped down completely). A person could build a fairly convincing kit around a Super Program, a DA 70, a DA 40, and a DA 16-45 with some caveats. The issue with this is that the Super Program doesn't let the user specifically control the aperture through the body; all shooting would be in modes like Program where the user is influencing aperture through setting of the exposure to drive the camera to use wider or smaller apertures (or possibly through monkeying with the ISO setting on a per-shot basis but that might not be such a great thing to do, or it might be a great solution, I don't know).
The MZ-S allows for user select-able aperture in-body. Either this body or the Super Program would be the Pentax cameras I would look at if I wanted to use more modern glass that does not offer aperture rings. Or I would consider leaving Pentax for my film kit, which I have to admit I have thought idly about once in a while, but I'm not nearly serious enough about film to do so.
I was planning to use the DA55 on a Super Program one of these days soon.
The PZ-1, and maybe the other PZ cameras, allow you to set the aperture using the now-common two-dial system. Probably also most of the MZ line allows you to set the aperture with on-body controls, though of varying levels of ease of use.
