Canon ET-67 Lens Hood

Lens hoods are primarily 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 some extra protection from accidental impact. Manufactured from non-breakable plastic. The ET-67 lens hood is designed for the Canon EF 100mm F/2.8 USM
