JJC LH-57 Lens hood is designed for Nikon AF-S NIKKOR 55-300mm f/4.5-5.6G ED VR Zoom Lens. Lens hoods are primarily designed to prevent unwanted stray light from entering the lens by extending and shading the end of the lens. JJC LH-57 Lens hood features a non-glare matte finish on the interior surface to further prevent or limit lens flare. In addition, since the end of the lens is extended, you also get the added benefit of some extra protection from accidental impact. This hood adopts a snap-on design, it attaches to your lens easily and will not scratch your valuable lens. The hood is also reversible to stay on lens when not in use. Now the original Nikon lens cap can be attached to the lens normally. JJC LH-57 Lens hood replaces Nikon HB-57 lens hood.
