Best for
A characterful vintage Leica telephoto system - the Telyt 200mm f/4.5 was designed for Leica's LTM screw-mount cameras (Leica III era), but the 200mm focal length is too long for accurate rangefinder focusing. The TZFOO (VISOFLEX precursor) is an accessory reflex housing that converts the Leica into a makeshift SLR for precise telephoto focusing. A collector-tier item for Leica enthusiasts.
