Zeiss Ikon ZM or M5

, and I know the ZM has a noisier shutter.

ZM sound is very nice and sweet 'clic', in fact not noisier, but little higher wavelenght becauce metal focal-plane. But in body have more plastic - thus good quality plastic I suppose.

Does the M3 have aa 0.58 or 0.72 viewfinder? How are the 28mm lines on it with glasses?

The M3 is a camera for 50mm or longer focal lengths; the VF magnification is 0.91x. It is perfect for use with my speedy 50. Forget about seeing the 28 or 35 brightlines, the M3 does NOT have them. With glasses, even seeing around the 50mm brightlines is hit/miss. When I use my M3, I wear contacts.
