This is the classic Micro-NIKKOR-P Auto 55mm f/3.5 lens, widely celebrated as one of the sharpest lenses Nikon ever produced. This version is the highly desired Non-Ai model featuring the Compensating Diaphragm (indicated by the colorful marks above the distance scale), which provided automatic exposure compensation on early non-TTL metering bodies.

The lens is exceptionally versatile, functioning as both an outstanding, sharp normal 55mm prime lens for general photography and a highly capable macro optic. It focuses continuously from infinity down to a 1:2 (half-life-size) reproduction ratio using its built-in dual-helicoid focusing system. The barrel clearly shows markings for 1:1, 1:15, and 1:2 (reproduction ratios).

This is a Non-Ai (pre-Ai) lens. It is fully compatible with older mechanical Nikon F, F2, and F3 bodies. For use on modern digital Nikon SLRs, an Ai-conversion is typically required to ensure full meter coupling and compatibility.
