GOI f. Leica M39 Teleobjektiv 5.5/135mm prototype *

In 1938, the Soviet optical industry started to develop interchangeable lenses for the FED cameras with the Leica M39 mount. The offered lens is one of the GOI prototypes of a rangefinder-coupled 135mm lens, constructed already in 1938. It is a compact, elegant design, with five elements in three groups and a non-rotating rangefinder cam. It never went to production in this form. The later 135mm lenses made by MKZ in Moscow were derivatives of Zeiss design. Like all prototypes by GOI, the lens also shows excellent build quality. It is in beautiful condition, with very good optics. It also comes with an original front cap. It is one of the rarest and most sophisticated Soviet lenses in Leica screw mount.
