ET-65III Lens Hood for the Canon EF 85mm f/1.8 USM, 135mm & 100-300mm
*The addition of a lens hood can help prevent flares--those circles of light that can accompany images where a strong light source is just outside the fame.*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.*This dedicated lens hood is designed to match the specific focal length of the lens it was designed for.package content:1x Lens Hood
