Hi Ed, The ZX-M was my first camera, and the 5n is my second, so I'm going the other way from you :-), but here's my .02 euros worth:
1. The mount is fine. I wouldn't hang a 600mm lens off it, but I have used it with my 24mm/f2.0 (around 400g) without any trouble. Okay it's polycarbonate, but so is bullet-proof glass: I don't believe Pentax would sell the camera with a plastic mount to save costs if it generated more returns because it wasn't able to hold their heavier lenses. Perversely, I think my 43mm/1.9 mates more snugly with the plastic mount on the MZ-M than the 5n's metal mount, but then I'm weird... 2. The M is a manual focus camera, so it doesn't need a circular polariser. If you don't have any polariser at all, get a circular to use on the M and/or 5n; if you want one for the M only, then a linear polariser is fine, and will produce better results. 3. The MZ-M's viewfinder is brighter than the 5n's, as it has a fully-reflective mirror sending light to it. The shutter and aperture info in the viewfinder can be hard to see in bright light, but is no worse than on the 5n. -- Kristian - This message is from the Pentax-Discuss Mail List.
