JJC LH-HN40 screw-in Lens Hood is designed to prevent unwanted stray light from entering the lens by extending and shading the end of the lens. The non-glare matte finish on the inside further prevents or limits lens flare. No vignetting will show with the hood on. The hood allows you to put on a Ф46mm filter and a Ф46mm lens cap. With the extended lens end, you will also benefit from extra protection from accidental impact. JJC LH-HN40 replaces NIK. HN-40 lens hood.
