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.

For Canon EF 75-300 f/4-5.6II and III, as well as EF 75-300 f/4-5.6II USM and III USM Lenses.

Does not fit 75-300 IS lens, which uses the ET 64II lens shade.
