Zenit-122B camera seems to be the simplified domestic version of the Zenit-122. The Z-122B differs from the 122 by lack of a self timer and a checked-up shutter construction. All the main units and mechanisms are installed in a metal body, the outer plastic plates serving for functional design of the camera. The minimum exposure time for providing the full opening a frame window is 1/30s. The film speed in ISO 16–500 range is introduced into an exposure meter with the help of the special limb. Winding and rewinding are executed in the manual mode. ZENIT-122B is complete with a new lens – MC Zenitar M2 2/50 [2].
