1960  JUPITER 8  2/50mm M39  RF Lens  Silver Edition    for your collection    Old  1960  Jupiter - 8  2/50  Lens    Silver Edition Krasnogorsk Optical Glass Factory,   KMZ                     for Leica Zorki FED  Rangefinder Cameras        Zeiss Sonnar 5.0cm f/2.8  COPY        The Jupiter-8 (sometimes marked in Cyrillic, ЮПИТЕР-8) is a postwar Soviet copy of the prewar Zeiss Sonnar 50mm f/2 for the Contax, built with six elements in three groups. It was made in Contax and M39 mounts, both for rangefinder cameras.    Without a doubt the strength of the lens is the image quality. Soviet optical factories were known for sharp optics, and this one is no exception. The edges are not so good but the center is.  The lens was originally available only in the natural rather dull "silver" of aluminium but in the 1970s was also made with a black finish. It belonged to the Soviet class of lenses which was named Jupiter.   Description Focal length - mm 52                                                              Geometrical relative aperture 1:2 Corner of a field of vision: 45 °                       The size of a shot: 24x36 mm Quantity of lenses/groups: 6/3                      Forward topmost focal length: −49,60 mm Back topmost focal length: 27,75 mm                        Distance from the first to last surface: 31,74 mm Light diameter of the first surface: Ø29,0 mm                      Light diameter of last surface: Ø22,0 mm Resolution (0мм/10 mm mm/20): 39/29/24 lines/mm              Resolution on THAT (centre/field): 30/14 lines/mm Enlightenment type: chemical, single-layered                        Limits of a scale of diaphragms: 1:2 - 1:22 Near limit of focusing: 1 m                               Working distance: 28,8 mm Lens with the camera thread : M39x1                        Weight: 130 gr     In good condition, works aperture throughout the range, the lenses are clean without fungus or dust. 1 light scratche on the front lens .
