Nikon HN-2 lens hood for 52mm Costar lens

The Nikon HN-2 lens hood was manufactured in Japan as an accessory for various Nikon lenses with a 52mm filter thread, including the 28mm f/2.8, 28mm f/3.5, and certain 35-70mm zoom lenses. It was designed to prevent lens flare by blocking stray light from entering the lens, thereby improving image contrast and color saturation. This particular accessory is highly valued by film photography enthusiasts and Nikon collectors who appreciate vintage camera equipment. The HN-2 hood is sought after for both its practical function in improving image quality and as an original accessory to complete vintage Nikon camera systems. Photography collectors particularly value these hoods when they're in good condition and properly paired with their intended lenses.
