Zeiss Ikon ZM lens mount_Mamiya NC Peer into the lensmount sideThe Zeiss Ikon ZM is a lovely M mount 35mm rangefinder camera, with a bright, clear viewfinder and aperture priority autoexposure a more modern, squarer M7, essentially. This one's in excellent condition, with accurate metering and shutter speeds, good rangefinder, and only very minor cosmetic wear, most notably a small scuff on the rear door and a small mark on the edge of the top plate: nothing dramatic.
