55mm Generic Petal Lens Hood for Canon Nikon Sigma

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 benefit 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. Besides The 52mm Petal Lens Hood is waiting for you on the online store.

It is a universal lens hood which fits for any 55mm 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).

But a tiny flaw maybe existed for some specific lens. The lens hood might block off parts of light source and form a slight dark angle in the periphery of picture when using wide-angle side. Beware of THIS!!
