This lens replaced its predecessor Industar-26m as a standard lens on the FED-3 and early FED-4 cameras. The optical design of the Industar-26m was improved and aperture stop-clicks were introduced.|
This is one of the newer multicoated LTM lens made by the Soviet (now Ukrainian) photo industry. It is sharp and contarsty, with smooth focusing action and the aperture click-stops. The lens later evolved in all-black Industar-61LD.
The lens was also made in universal 42mm mount for Zenit cameras, named Industar-61L/Z. It was my favorite 50 mm lens for years, and I still keep it, even though I am not using my 42 mm mount SLRs anymore.
