Overview

The Nikon Ultra-Micro-Nikkor 125mm f/2.8 is an exotic, rare industrial lens from 1965, designed for semiconductor photomask production with extreme resolution (400 lines/mm) and minimal distortion (-0.3%). It delivers outstanding sharpness at wide apertures, producing a soft, veiled background quality ideal for close-up photography. However, it requires complex adaptation for modern cameras, with metering issues and limited compatibility. Its heavy, black barrel uses 72mm filters. Best suited for enthusiasts willing to modify equipment for unique close-up rendering.
