Industar
Industar was a lineup of photo and video camera lenses, manufactured in the former Soviet Union from mid 1930s through late 1990s. Many of the Industar designs trace their roots to pre-WWII Calr Zeiss and Leica lens designs. Most notably, Industar-22, Industar-50, Industar-61 were all derived from Carl Zeiss 4 element, 3 group Tessar design. Industar lenses were manufactured at FED factory in Kharkiv (sometimes bearing FED markings instead of Industar), KMZ factory in Krasnogorsk, KOMZ factory in Kazan and LZOS factory in Lytkarino. The numbering of individual models does not seem to relate to the sequence of production in any way, as some higher numbered Industar models have earlier years of production than some of the lower sequenced ones. Some Industar models were produced in a very limited batches and never made to mass-production. Early lenses were manufactured exclusively for the internal market, but starting in mid 50s a few models, most notably Industar-50 and Industar-26m, were also exported to the West, often as a bundled lens for Zorki rangefinder cameras.
