Canon EW-72 Lens Hood for EF 35mm f/2.0 IS USM Lens

The Canon EW-72 Lens Hood is for the EF 35mm f/2 IS USM Lens. It is a black, petal-style lens hood made to keep undesired side lighting from entering the lens. It does this by extending and shading the end of the lens. Furthermore, since the since the hood extends from the lens, it gives extra protection from accidental impact.
