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 frame
Blocks Stray Light - Prevents Flare in Your Images - Protects Lens from Accidental Impact
Fits all 55mm and 58mm lenses - Please verify your camera's lens thread size before ordering. Your camera's lens thread size will be marked somewhere on the lens barrel or printed underneath your lens cap. This number is always preceded by a "Ø" (diameter) symbol.
Universal Professional Tulip Lens Hood is primarily designed to prevent unwanted stray light (flare) 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. Screw-mount lens hoods, such as this 55mm, are designed to screw right into your lens or filter. Rear locking ring allows the user to rotate the hood in 360°direction.
