The Lens Hood is one of the most important accessory you need for each lens you own.A lens hood provides multiple functions: preventing image-degrading lens flare by blocking stray light from striking the surface of the lens, it enables your lens to give you the sharpest photographs with the best contrast and most vivid colors, in inclement weather, it can assist in keeping moisture or wind-blown debris off the lens; and it protects the front barrel from the inevitable impacts against walls, door frames, and other real-life obstacles.
