The Industar-50 is a screw-mount lens for 35mm rangefinder cameras. The lenses were made since 1959 by KMZ, mainly as M39 39mm screw-mount standard lens for the Zorki camera series. Older variants (ancient Leica lens style) were made by LZOS. There is also a M42 variant Industar-50-2 for SLRs. This m42 copy is popular as "pan-cake" lens on modern SLR bodies. The Industar-50 is a 50mm f3.5 lens, based on the Zeiss's Tessar 4-element lens. The brand name Industar was used for all similar 4-element/3-group lens constructions of the whole soviet photo-optical industry.
