hi matt, sorry for taking so long to reply. i haven't had much time to use the camera, so i didn't really feel like i could answer any of your questions.
i've since put a couple of rolls through it, and right now i have mixed feelings about the camera. the lens is great, and the slides look wonderful. but the camera handling is a little irritating - stuff like not retaining the ev compensation settings after power down, the loud film advance and focusing sounds...
i guess we're back to what everyone says about this... it's a great giant point-and-shoot. and whether that's good or bad depends on what you want. i'm taking it on a long trip as a second camera to see how it fares. at the end of this, i may decide to switch to one of the manual focus mamiya mf rangefinders.
as for the zoom version, sorry never seen one so can't say.
