Nippon Kogaku 50mm f2 Nikkor-H brand_Calypso but with its front-mounted shutterThis is a clean early Nikon standard lens not so early that theyre calling it a 5cm, but early enough that its still branded Nippon Kogaku. In excellent cosmetic condition, except for some wear on the front nameplate ring. Clean glass, good mechanical function. Note that this is a pre AI lens, so camera compatibility will be limited; check your cameras instruction manual (or ask us) to be sure.
