Luiz Paracampo	Posted - May 06 2011 : 04:16:31 AM This very strange Russian lens prototype developed to be used in Kiev /Contax bayonet has no name, but fixed 1:8 aperture with no diaphragm settings, but rangefinder coupled. Has minimum 2,2m close focusing This estrange lens was sold by Leica Shop through Westlicht auction around 2004 it was announced as being a 2/75mm Russian lens for Contax LP http://www.ussrphoto.com/UserContent/652011_Russian 75.JPG

Luiz Paracampo	Posted - May 07 2011 : 2:58:06 PM Juhani As I did see in the second picture, when mounted in a Zenit E camera, the Jupiter 38 seems to have a diaphragm scale. This unnamed lens for Kiev has no scale at all! one could not try to change diaphragm unless desasembing the lens! Regards LP
cedricfan	Posted - May 06 2011 : 07:11:41 AM Idea is same that was used in Selena traffic camera lenses: 75mm lens and fixed aperture but normal focusing system. See: http://www.ussrphoto.com/Wiki/default.asp?WikiCatID=26&ParentID=2&ContentID=1099&Item=JUPITER-38+75mm%2Ff%3A4+M42 So maybe this was also for some kind of special use where lens is focused for one spot and aperture adjustment is unnecessary? Best regards, Juhani
