Nikon 5cm (50mm) f/2 Nikkor-H.C Nippon Kogaku Japan Lens for M39 Screw Mount, Chrome Review

The Nikon 5cm f/2 Nikkor-H.C is a vintage M39 screw mount lens from Nippon Kogaku Japan, offered here in used bargain condition with a 40.5mm filter thread. As a legacy optic, it was designed for rangefinder cameras with M39 (Leica Thread Mount) compatibility and can be adapted to modern mirrorless bodies for those seeking classic rendering and manual focus control.

At $219 in bargain condition, this lens represents an affordable entry point into vintage Nikon glass for collectors or shooters drawn to the aesthetic and build quality of mid-century Japanese optics. The f/2 maximum aperture offers moderate speed for low light and shallow depth of field work, though buyers should expect the typical handling and optical quirks of legacy glass, including manual focus and potential issues like haze, fungus, or coating wear given the bargain grade designation from KEH.
