This is a legendary optic and a superb collector’s kit: the NIKKOR-P.C Auto 105mm f/2.5 (marked as 105 cm), widely recognized as one of Nikon’s sharpest and most famous portrait lenses. This version is the P.C. (Penta, Coated) type, featuring factory multicoating for superior contrast and flare control.

The lens delivers a classic portrait perspective with shallow depth-of-field, perfect for film photographers using vintage Nikon SLRs. The lens is equipped with a specialized mounting/focusing unit (visible at the base) which is either a short extension tube or a dedicated focusing helicoid, enhancing its versatility.

This is a Non-Ai (pre-Ai) lens, identified by the solid metal coupling prong. It is 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.
