Canon ET-65B Lens Hood for EF 70-300mm f/4.5-5.6 IS and DO IS USM Lenses

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. The Canon ET65B lens hood is designed to fit Canon EF 70-300 f4-5.6 DO IS USM and 70-300 f4-5.6 IS USM lenses.

Lens hoods are primarily designed to prevent unwanted stray light from entering by extending and shading the end of the lens, ensuring no problems with vignetting or motor functions. Additionally, since the end of the lens is extended, you also get the added benefit of some extra protection from accidental impact. Lens hoods match the specific focal length of the lens it was designed for.

This lens hood fits the following Canon lenses:

• EF 70-300mm f4.5-5.6 DO IS USM
• EF 70-300mm f4-5.6 IS USM
