Jupiter-37A (Юпитер-37A), black lens for SLR camera 135 mm, f/3.5, M42 mount, s/n 873549, Kazansky Optical Mechanical Plant (KOMZ), Kazan', USSR, 1987 Very good condition. Lens is clear and clean, does not have any fungus or scratches.Inside there are microspecks of microdust. Aperture and focus rings rotate properly and fluently. Aperture blades have a bit oil. Body has signs of age and use. I took test photo with this lens set on DSLR "A-100" via adapter. Test photo is the last one. "Jupiter-37A" is USSR high-speed fixed manual telelens which was based on German Carl Zeiss Sonnar 3.5/135. Letter "A" means that with adapter this lens can be mounted on camera with mounts: M39*1/45.2, bayonet H (Nikon F), bayonet K (Pentax K-mount) and others. It was produced at KOMZ since 1978 till 2009. This lens has one-layered anti-reflection coating. Lens has 12 aperture blades which form ideal round hole. Aperture meaning is changed fluently, not discrete. Body is fully metallic. Lens has warm colour reproduction. Photo with this lens is extremely sharp and three-dimensional. Background is blurred very nice. Lens does not like contre-jour and side light, so lens hood is recommended. It is one of the best USSR portrait lenses. Variants: "MC Jupiter-37A" was produced in 1983-89, has multilayered anti-reflection coating "Jupiter-37A MC-H-30" was produced in 1983, has multilayered anti-reflection coating "Jupiter-37AM" and "MC Jupiter-37AM" - produced since 1990 till 2002, changed body and lowered weight. "MC Jupiter-37K" - produced since 1985, Pentax K-mount. Price for this lens was rather high and depended greatly on type of anti-reflection coating: 55 Soviet Roubles for usual "Jupiter-37a" and 100 Soviet Roubles for "MC" version. Average salary was 120 Soviet Roubles per month. Lens offered has "USSR Quality Mark" meaning that this lens has higher quality than ordinary lenses.
