Canon EW-54II Lens Hood for Canon EF 35-80mm & EF 35-80mm USM SLR Lens
Canon lens hoods are one of the most important accessories for each lens you own. 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.
