The Jupiter-9 8.5cm f2 is a Soviet-made short telephoto lens based on the classic Zeiss Sonnar design. Cosmetic condition is decent, with some wear and tarnishing of the aluminum barrel; focusing action is reliable but slightly underdamped; the fully manual diaphragm works well. Image quality is the big deal here, with a lovely soft glow wide open and some mighty fine-looking out-of-focus area rendering. The lens sharpens up well a few stops in, so you have options if you’d prefer something a bit less dreamy. This lens is in a Nikon F mount, infinity adjusted, and suitable for use on most Nikon cameras or F-mount adapters. Includes original Bakelite case.
