Wide-angle lens. Fitted with iris diaphragm. Coated optics. Designed for rangefinder cameras such as "Zorki", produced and bayonet option for rangefinder camera "Kiev". Based on the Zeiss lens Biogon 2,8 / 35. Originally was called "BK-35" (Biogon Krasnogorsk). In addition to KMZ Jupiter-12 produced Lytkarino optical glass (LZOS). On plant production Krasnogorsk lenses "Jupiter-12 BK" began in 1947 on the basis of optical units, supplied by East Germany on reparations.
