GOI Teleobektiv 5,5/13,5cm M39

GOI Leningrad Teleobektiv 5,5/13,5cm is one of the first Soviet telephoto lenses in Leica M39 mount, made as a prototype for the earliest black Fedka cameras.

An interesting feature of this special lens is the retrofocus design – quite unique for a Pre-WWII optical photo-lens construction - the lens keeps the same length when focused.

Judging by the serial number the lens was made about 1935 – it wasn't until 1938 when interchangeable lenses for FED cameras began to be mass-produced at other Soviet factories.

The lens is in very good condition, comes with an original GOI wooden box with matching serial number.
