Description: A lens hood provides multiple functions: it shades the lens from stray light, improving
your contrast and image quality; in inclement weather, it can assist in keeping moisture
or wind-blown debris off the lens; and it protects the front barrel from the inevitable
impacts against walls, door frames, and other real-life obstacles. Almost all EF
and TS-E lenses have a Canon lens hood engineered specifically for it.
