Canon ES71 II Lens Hood for EF 50mm f/1.4 Lens - 2660A001
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. This ES-71II Lens Hood from Canon is
compatible with the Canon EF 50mm f/1.4 USM Lens and features a black
felt interior lining to absorb light and therefore reduce unwanted light
reaching the lens.
