This is a vintage lens made in the former Soviet Union (USSR). The optical layout of the JUPITER-9 2/85 was copied from Carl Zeiss Jena Sonnar 2/85. JUPITER-9 2/85 is soundly assembled – all made of metal and glass. The focus ring rotates smoothly. During focusing, the front lens does not rotate, and the frame of the body moves forward. The focus ring rotates 270 degrees. During focusing, the entire lens unit moves. The minimum focusing distance is 80 cm. The lens has an installation ring and aperture preset ring. The setting ring can take one of the following fixed values: F / 2, 2.8, 4, 5.6, 8, 11, 16. The preset ring rotates smoothly and with this you can set any value of the number F. There is also a DOF scale for the same values of the number F as on the aperture setting ring. It is very nice that the diaphragm consists of as many as 15 petals. The lens has been professionally serviced and tested, we have done everything necessary for proper operation, cleaned, lubricated, adjusted (CLA). Optical element (glass) in excellent condition, clean and transparent. The blades of the diaphragm are clean and free of oil (this is very important for proper operation).
