Industar-50 was a very successful Soviet made lens. It was a standard
or optional lens on practically every Zorki camera, from Zorki-S in the mid
50's to Zorki-4K in the mid 70's. The lens was also made in a 39 and 42 mm SLR
mount and was installed (standard or option) on every Zenit model as well, from
Zenit-S to Zenit-E. It came in different shapes and finishes, from a chrome
collapsible Elmar-style lens to a black "flat" Zenit lens. The optical formula
was always the same, the lens produced sharp and contasty images.
This Industar-50 is the newer, rigid barrel design used on the Zorki-4, Zorki-5, Zorki-6 and Mir.
- Focal length: 50 mm, coated glass, chrome finish.
- Maximum aperture - 1:3.5 (settings from 3.5 to 16).
- The lens couples with a RF of any threadmount Leica or Leica copy.
The glass is clear and clean, the finish is clean overall, there are several
blemishes on the chrome coating. Focusing and aperture are smooth.
The Industar-50 is shown mounted on a Leica IIIa (not included).
