ABOUT ITEM'S ORIGIN (You can SKIP it!) Industar-50 is a normal angle (standard) coated lens issued at USSR since 1950s years for RF Leica copies, then for SLR Zenit cameras... very simple, compact and sharp... just one of Zeiss Tessar copies. Industar-50-2 is slightly improved lens for M42 Zenit, Practica, Pentax, Chinon, Cosina, Yashica, Bessaflex and other SLR cameras with same lens mount. Interesting thing that Industar-50 for M42 lens mount is rare lens: you will see a lot of Industar-50-2, but not Industar-50!
