The Jupiter 9 is an 85 mm f/2 lens made in the Soviet Union. It is based on the design of the Carl Zeiss Sonnar, after the technical information, and machinery were taken from Carl Zeiss in reparations at the end of the Second World War. Production began in 1948, when the lens was initially called the ЗК-85 (Sonnar Kransogorsk) and it was assembled using mostly German parts in Contax/Kiev mount. The lens was also adapted to Zorki (M39) mount to fit the Zorki cameras early in production.[1] [2] It appears, for both Zorki and Kiev mount, in a 1949 catalogue.[3] By 1951 the name changes to Jupiter 9 (Юпитер-9).[2]
The lens has seven glass elements in three groups; a single glass at the front, and two cemented groups of three. All versions of the lens are coated.
It was made by the KMZ and LZOS factories, in Leica 39 mm thread mount for Fed and Zorki rangefinders, but originally it was a Contax bayonet used in Kiev cameras.{ref name="Jup9Page"/>
