Jupiter is a family of Zonnar-type anastigmat photographic lenses produced in the USSR since 1948. Most "Jupiters" are designed for small format cameras, but some cinematographic lenses, as well as optics for special types of equipment, bear the same name. Bayonet Contax RF (from the English. Rangefinder - rangefinder) - a bayonet connection of interchangeable lenses, developed by the German company Zeiss Ikon for small-format rangefinder cameras "Contax" in 1932. The Contax RF standard is used to this day, including in Japanese Voigtlander rangefinder cameras. For several decades, the mount was used in Soviet photographic equipment of the Kyiv brand, the production of which was established at the Arsenal plant on equipment exported from Germany as reparations. Bayonet Contax RF of the Soviet camera "Kyiv-4". On the swivel ring of the inner mount there is a meter scale, and on the fixed ring of the outer mount there is a depth of field scale. Both scales are for standard lenses only. In the Soviet Union, the mount did not have any name, since it was used in only one type of photographic equipment produced by one manufacturer. After the collapse of the USSR, the Kyiv-Contax bayonet designation became widespread in the CIS, taking into account the huge number of Soviet optics that support this standard. In Japan, in the 1950s and 1960s, the Nippon Kogaku company produced a line of Nikon S rangefinder cameras with a mount that was an exact copy of the Contax RF mount. The difference was in a different gear ratio of the kinematic connection between the rangefinder and the inner ring of the bayonet, leading to inaccurate focusing of the Contax lenses at finite distances. Because of this difference, the mount got its own name Nikon S. Lenses intended for installation in the Contax RF mount are designated in Japan with the symbol “C”, while “native” Nikon ones are marked with “S”. Both can be installed in the Nikon S mount, but German focusing will only be accurate at infinity. ---------------------------------- The buyer will receive exactly the same item as in the photo.
