Leitz Telyt 1:3.4/180 mm Prototyp* / Leitz Telyt 180 mm f/3.4 Prototype*

Extremely rare Leitz Canada experimental unit of a 180 mm lens for the Leica M. Based on computation C47 by Dr. Walter Mandler. With rangefinder coupling and „goggels“ for viewfinder and rangefinder. Only a very few prototypes were made of this version, and there was no later market launch. Very nice condition. A small particle inclusion in the optics and a very small scratch on the front element, otherwise clean.
