_x005f_x000D_ This Lens Hood, like all other Lens hoods, is 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 of some extra protection from accidental impact. It opens as needed to prevent lens flare problems. It comes with an adjustment ring to ensure proper mounting orientation of the hood on your camera. It is a universal lens hood which fits for any 52mm filter size lens, also it can be used with a filter and a snap-on lens cap while many lens hood didn't have such function (as the picture above shows).

Beware of THIS!! The lens hood is compatible with any 52mm filter size lens. _x005f_x000D_ _x005f_x000D_ Specification: _x005f_x000D_ Origin: Mainland China _x005f_x000D_ Suitable for Canon, NIKON, compatible with SONY _x005f_x000D_ Model Number: Camera Lens Hood _x005f_x000D_ _x005f_x000D_ Note: _x005f_x000D_ 1.
