Industar-22

The Industar-22 is a lens of standard length produced for a number of 35 mm cameras made in the Soviet Union in the 1950s. It is a 50 mm f/3.5 Tessar-formula lens. It was first made as a collapsible lens in Leica 39 mm screw-mount, for the Fed and Zorki rangefinders.

A rigid model was made for the Zenit 1 SLR. This also has a 39 mm screw mount, but is substantially shorter than the collapsible model because the body of the Zenit is deeper than the rangefinder cameras, to accommodate its mirror.
