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 Flower hood provides excellent shading of lens from light rays that enter from the rectangular frame outside the image view. The Flower hood maximizes amount of hood coverage over lens for the minimum amount of hood area and weight.
Beautifully designed, this hood fits any lens/filter with thread size 77mm. It covers 24mm wide angle (equivalent to 35mm camera) to give optimum coverage and also adds a professional look to camera.
