ORIGIN AND MAIN FEATURES OF THE CAMERA
Basically inspired on the German 1932 Leica IId with L39 thread, the FED-4 (in spite of
preserving such classic LTM mount so as to be able to use the wide range of already existing lenses and a shutter being a copy of the German original one from the quoted Leica IId together with similar control knobs and dials) also sports some aesthetic aspects (specially the frontal part) linked to the mythical German M Series Rangefinder Leicas, the 1954 Leica M3 above all.
