Its production started in 1949. Lens is famous for its small size, blurring of unfocused zones, good sharpness and contrast. Jupiter-11 is probably the best USSR portrait lens.

In USSR this lens had possible mounts: M39 (for rangefinders), M39 (for SLR), M42 (for SLR), Contax RF (for rangefinders), special bayonet for Kiev-10 and -15 (for SLR - this lens). Also KOMZ (Kazan, USSR) produced a variant "Jupiter-11A" with changeable adapter.
