Hi Dan, I've have both. I'd way get the ZX-M first. Better metering, any mode DOF preview, ISO override, exposure compensation, shutter and aperture priority auto, speeds down to 30 seconds vs 1 second, and up to 1/2000 vs 1/1000. Viewfinder is smaller but brighter, and works well with slower lenses (think stopped down screw mounts with k adapter) and has better layout (I think) and more information, including a far superior manual metering interface. Also the mirror slap isn't seismic like the P3's
That's what I can think of off the top of my head, but I think it's a no brainer. YMMV. William in Utah. 11/14/2002 3:58:07 PM, "Dan Scott" <[EMAIL PROTECTED]> wrote: >Any reason why a user should prefer one over the other in equivalent >"used" condition? > >Dan Scott > > >
