Nippon Kogaku 5cm f2 Nikkor-H.C for LTM brand_Olympus a compartment for a laptopThis is the unusual "black belt" version of the classic Nippon Kogaku 5cm f2 lens for Leica thread mount: similar to the all chrome version, except the aperture ring is painted black with white engraved numbers. Clean glass, smooth focusing, and excellent cosmetic condition, with only very minor cosmetic wear. Includes an original black Nicca cap, too.
