The FED 2 was a 35 mm rangefinder camera introduced in 1955 by FED. The name of FED comes from the initial of Felix Edmundovich Dzerzhinsky. The FED 2 is a new design that is quite different from the FED 1. It has a longer rangefinder base (67 mm), a combined viewfinder and rangefinder window, adjustable diopter for the viewing window, a self timer, and a detachable back for film loading. The Jupiter-8 (sometimes marked in Cyrillic, ЮПИТЕР-8) is a 50 mm f/2 lens made by KMZ in the years after the Second World War.[1] It is a close copy of the Zeiss Sonnar, with six elements in three groups; the Soviet Union took the design data for several Zeiss products in War reparations (equipment, and even staff, were also taken to the Soviet Union). The Sonnar had been the standard lens for the Contax, and the J-8 became the standard lens for the Kiev, the Soviet copy of it.
