Tamron 2C9FH Lens Hood for SP 90mm F2.8 Di Macro Lens
Overview:
- For Tamron SP 90mm f/2.8 Di Macro Autofocus Lens
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.
