The Phot-R 37mm Wide-Angle Metal Lens Hood is specifically designed for Wide-Angle (zoom) Lenses. The Lens Hood has a screw mount fits over any 37mm lens filter or barrel thread.
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.
The Phot-R Lens Hood is made from solid lightweight aluminum metal and has a high quality smooth black finish.
It is designed for wide-angle (zoom) lenses with angles of view up to 70° wide (approx. 28mm in 35mm format).
Phot-R products come with a 1 year limited warranty.
