Nikon 55mm f3.5 Micro-Nikkor with PK-3 wind This is a modular extensionThis Nikon 55mm f3. 5 Micro Nikkor is a pre AI macro lens for Nikon F mount cameras. Some internal dust, good focusing and diaphragm action. Cosmetic condition is good, with some paint and finish wear. Because this is a pre AI lens, compatibility with modern Nikon DSLRs will be limited, but it should work well on most adapters. This lens provides magnification up to 1: 2, on its own, and 1: 1 with the included PK 3 extension tube.
