Nikon HB-35 Bayonet Lens Hood for Nikon 18-200mm f/3.5-5.6G VR II DX AF-S Optimize the lighting in every photo taken. The Nikon HB-35 Bayonet Lens Hood is made specifically for the Nikon 18-200mm f/3.5-5.6G VR II DX AF-S Lens. It 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. The petal shape of this lens hood maximizes the amount of hood coverage for the minimum amount of weight and hood area.
