Lens Hood (ET-83C) for Canon EF 100-400mm
f4.5-5.6L IS Lens
Lens hood is designed to prevent unwanted stray
light from entering the lens by extending and shading the end of the lens.
But, since the end of the lens is extended, you
also get the added benefit of some extra protection from accidental impact if
you drop the lens.
