New Canon EW-73D Camera Lens Hood for EF-S 18 - 135mm f/3.5-5.6 IS USM Zoom Lens

The Canon EW-73D Lens Hood for the EF-S 18-135mm f/3.5-5.6 IS USM lens is designed to prevent unwanted stray light from entering the lens by extending and shading the end of the lens. In addition, since the end of the lens is extended, you also get the added benefit of extra protection from accidental impact.
