NO RETURN Applicable If The Seal is Broken

The dedicatedNikon HB-47 Lens Hoodis specifically designed for use with the AF-S 50mm f/1.4G lens.

Lens hoods are primarily designed to prevent unwanted stray light from entering the lens by extending and shading the end of the lens. In addition, since the end of the lens is extended, you also get the added benefit of some extra protection from accidental impact.
