Description
This lens hood is designed to fit the Canon Ef 50MM 1.8 II lens and is specifically designed to prevent unwanted stray light from entering the lens. It also extends the end of the lens to provide added protection from accidental impact.
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. Dedicated lens hoods are designed to match the specific focal length of the lens it was designed for.
