GOI Leningrad f. M39 Teleobjektiv 5.5/13.5cm

One of the very first Soviet telephoto lenses in M39 mount, produced as a prototype exclusively for the earliest black FED cameras. A remarkable feature of this special lens is its retrofocus design – highly unusual for a pre-war construction – which allows the lens to maintain the same physical length when focused. Based on the serial number, it was manufactured around 1935, several years before interchangeable lenses for FED cameras began to be mass-produced at other Soviet factories (from 1938 onwards).

The offered lens is in very good condition and is accompanied by its original GOI wooden keeper with matching serial number.
