Industar-22 Lens in Leica Threadmount
The Industar-22 design was "borrowed" from Leitz Elmar. It was an improved version of a prewar collapsible FED lens (also known as Industar-10).
The Industar-22 was a standard lens on the early Zorki cameras (Zorki, Zorki-S, some of Zorki-2S') and was also a popular enlarger lens in the USSR in the 60's.
