CAM-X EW-73D Lens Hood for EF-S 18-135mm f/3.5-5.6 is USM Lens Hood for Canon 80D 7DII 7D2 77D 760D Lens Hood  (67 mm, Black)

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. Designed for use with the EF-S 18-135mm f/3.5-5.6 IS USM lens and Canon RF 24-105mm F4-7.1 IS STM Lens.
