ABOUT ITEM'S ORIGIN (You can SKIP it!) Jupiter-37A was based at ideas and optical scheme of previous Jupiter-11 series lenses. In turn, Jupiter-11 lens is a copy of 135mm Sonnar Carl Zeiss lens, issued in 1930th years at Germany for RF cameras like Leica and Contax. First 35mm Russian post-WW2 lenses for RF cameras (known as BK and ZK lenses) were created at KMZ plant on the base of of Zeiss and Leica equipment, which was imported to the USSR for production towards reparations after WW2. All the Soviet plants which issued photo equipment (include most famous KMZ, LOMO and Litkarino plants) mostly issued military equipment, and little part only were for civil purposes, and those civil goods had enough high quality to receive World glory for best ratio price/quality. In the main, most all Soviet lenses are exceptionally good and this one is no exception! It can be used with a lot of digital SLR & MFT cameras with simple and inexpensive adapters. ITEM'S CONDITION: AS-IS, WELL-USABLE The lens looks never used before, still with original paper. The glass is very clean, without scratches, separations or fungus, but you will find a lot of very tiny bubbles (presented at item's photos), looks like defect of gluing two optical elements. At some situations it can impact on image quality (will drive it to low contrast). Aperture blades open and close smoothly, focusing is smooth too. The lens looks fine cosmetically, just examine item's photos, please. All functions are available even with mentioned above negative feature.
