ET-60 II Lens Hood For Canon

The ET-60 II Lens Hood is primarily designed for Canon EF 75-300MM F/4-5.6 III EF-S 55-250mm f/4-5.6 IS 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.
