ThePremium Tulip Petal Lens Hoodhelps prevent flares, reduces glare, and the Tulip design is perfect for standard and zoom lenses. Threaded mount screws directy onto your lens or filter.The addition of a lens hood can help prevent flares--those circles of light that can accompany images where a strong light source is just outside the fame. These type of lens flares occur when indirect light rays pass through the front lens elements but don't make it all the way through to the image sensor.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.This lens hood maximizes the amount of hood coverage for the minimum amount of weight and hood area because of its "petal" shape.Package Includes:- UltraPro Premium Petal Shape Lens Hood- Lens Pen Cleaning Accessory- Lens Cap Keeper
