When using wide-angle lenses on the Ikon rangefinder camera, users may want to pick up a ZI Viewfinder from ZEISS in order to ensure accurate framing. This optical finder is designed to demonstrate the perspective of 25/28mm lenses, which provide a wider angle of view than the Ikon's integrated rangefinder. Photographers can use this to check framing while the rangefinder can be used to confirm focus. Also, it easily attaches to the camera's hot shoe.

Q: 10. Does the optica rangefinder work normally for focusing at 50cm or closer than 70cm it's necessary to use live view?

A: The focusing range for ZEISS ZM lenses is limited by the rangefinder camera and not the lens itself. Most rangefinder coupled focus systems are limited to a minimum focus distance of 0.7m, even though the lens is capable of focusing closer. When the ZM lenses are mounted to a mirrorless camera via an adapter, then the minimum focus distance is determined by the lens and not limited by the camera.
