GOI f. Fed M39 Orion 6/2.8cm prototype *

In 1944, shortly after the GOI factory resumed operations following its wartime evacuation, the optical institute began developing new lenses for FED cameras. We are pleased to offer an extremely rare prototype of the Orion wide-angle lens, equipped with a coupled M39 screw mount designed specifically for FED rangefinder cameras. This early experimental lens predates by many years the later serial production of the Orion-15 28mm f/6, which was eventually manufactured at the KMZ plant in the Soviet Union. The offered lens is engraved on the barrel with 'OB-244' and is preserved in beautiful, near-mint condition.
