The Jupiter 13 125 mm f/ 1.5 (Russian: "Юпитер") is a rare Soviet superfast prime lens. Alongside with the Carl Zeiss Jena Sonnar 125/1.5, it is considered to be the fastest lens for that focal length.
It is basically used in astrophotography and for night-vision systems.
Due to production difficulties it was produced in small lots only at the KMZ.
The lens is capable of covering a 9х12 frame. Hence, it can be used with medium format cameras as well as cardan and format cameras.
