The specially designed EW-83 II lens hood is suitable for use with:

• Canon EF 20-35mm f/3.5-4.5

Lens hoods are primarily designed to prevent unwanted light from entering the lens, extending and shading the end of the lens. A specific lens hood is designed to fit perfectly with the particular focal length of the lens for which it is designed. Additionally, this hood features a matte finish on its interior to prevent or reduce light reflection. Furthermore, as the end of the lens is extendable, it provides extra protection against accidental impacts. The sturdy base of the hood also allows it to be reversed, making it easier to store the lens in a more compact manner.
