50mm lenses for Kiev
The standard lenses of Kiev (Contax) have the characteristic of not being provided with a focusing system, the helicoid is included in the body, the focus can be adjusted using a toothed wheel, also coupled to the rangefinder. The mount is a bayonet, there is another bayonet, external, for the other focal lengths, which have their own focusing helicoid.
Peculiarity: the diaphragm controls are notched on the lenses for Kiev, never on the lenses for Zorki.
