Jupiter (lens)

The Jupiter (Russian: Юпитер, "Jupiter") series of lenses are Russian camera lenses made by KMZ during the Soviet era. They were made to fit various cameras of the time, including the Leica and the early Zeiss Contax rangefinder cameras. They are copied from Zeiss prewar designs, with incremental improvements such as coatings introduced during production.

This article is about the camera lens. For other uses, see Jupiter (disambiguation).

Jupiter-8

Jupiter-8M in Contax mount

The Jupiter-8 is derived from the Zeiss Sonnar design, and was used as a standard lens on the Zorki and Kiev cameras.[1] It has six elements in three groups, a maximum aperture of f/2, and focuses down to one metre, similar to other standard lenses of its time.[2] The Jupiter-8M variant, depicted, was modified to have detents (click-stops) in the aperture ring, and was only made for the Kiev camera.[3]

Jupiter-9

The Jupiter-9, like the Jupiter-8, is derived from the Sonnar design, and is a fast telephoto lens. It was made available in the Leica and Contax mounts, as well as in the M42 lens mount used by the Zenit cameras. It has a focal length of 85mm and a maximum aperture of f/2.[4] It has seven elements in three groups.[5]
