Canon lens hood EW-83E

Model number:Canon lens hood EW-83E Compatible models: EF-S10-22mm F3.5-4.5 USM, EF16-35mm F2.8L USM, EF17-40mm F4L USM Description: A lens hood that blocks unnecessary light from outside the angle of view and prevents flare and ghosting that can cause image quality deterioration. The optimal shape for each lens creates a comfortable shooting environment. 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. The "petal" shape of this lens hood maximizes the amount of hood coverage for the minimum amount of weight and hood area. This dedicated lens hood is designed to match the specific focal length of the lens it was designed for.
