Nikon 55mm f3.5 Micro-Nikkor-P with M2 (converted pre-AI) lens mount_Nikon F and pushbutton startThis Nikon 55mm f3. 5 Micro Nikkor P is in good cosmetic condition, with some paint wear from use and handling. Focusing is good, diaphragm moves well, and the optics are clean, with minor dust. Provides 1: 1 magnification with the included M2 extension tube, 1: 2 without. This is a pre AI lens that has been converted to AI with original Nikon parts, so it will work on any modern F mount camera, though function will vary.
