GSI Super Quality Lens Hood for Nikon 18-55mm f3.5-5.6G ED AF-S DX Nikkor zoom lens - Functions Exactly as the Nikon HB-33, Provides Protection from Light and Impact
This GSI Lens Hood is 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. Fits the lens perfectly. Great affordable alternative to the Nikon HB-33.
