Lens hoods are
primarily designed to prevent unwanted stray light from entering the
lens, by extending and shading the end of the lens. A dedicated lens
hood is designed to perfectly match the specific focal length of the
lens it was designed for. Moreover, this hood features a non-glare
matte finish on the interior surface, to further prevent or limit lens
flare. And since the end of the lens is extended, you also get the
added benefit of some extra protection from accidental impact. The
bayonet mount is designed to also work in the reversed position,
allowing the hood to be placed backwards over the lens for a more
compact storage solution.
