The Zenit-B (ЗЕНИТ-B, B = V in Latin] was one of a long series of M42 screw mount Zenit cameras from KMZ. Zenit means Zenith, a point in the sky that appears directly above the observer.

The Zenit-B was a purely mechanical 35mm SLR similar to the Zenit E but without the light meter. Like the E, it had no automatic diaphragm; the lens had to be stopped down manually after focusing. There were also no focusing aids apart from the plain ground-glass screen.

Mostly available in a chrome-topped design, there were also some all-black models. As with the Zenit E, a small number of B cameras were made in M39 screw mount.

All Zenit-B produced between 1968-73 with quantity of 889.617 units. There are 15 types of the camera. [1]

It could be found under export names: Revueflex-B, Kalimar SR100, Phokina, Prinzflex 500, Meprozenit-Pro, Cambron-B, Global.
