Adorama Dedicated Lens Hood for Canon EF 85mm f/1.2L, 80-200mm f/2.8L Lenses (ES-79II)
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.
