Description
The Fotodiox Dedicated Bayonet Lens Hood is designed for Nikon 18-135MM Dx and 18-70MM F 3.5-4.6G lenses, replacing the Nikon HB-32. Its main purpose is to prevent stray light from entering the lens and provide extra protection from accidental impact. It is specifically designed to match the focal length of the lens it was made for.
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.
