This is a rare prewar FED telephoto lens, 100mm f:6.3. The lens is clean and smooth mechanically, the glass is also clean.
The lens was made in the late 1930's by the FED commune. It is exceptionally well finished and comes with metal rear and front caps. The case is made of cardboard covered by fabric.
This is the first 100mm FED lens appearance in the Fedka.com store.
