In addition, since the end of the lens is lengthened, you also get the added advantage of some additional safety from unintentional impact. The "petal" shape of Canon EW-83E maximizes the amount of hood coverage for the minimum amount of weight and hood area. The Canon EW-83E hood is developed to match the specific focal length of the lens it was designed for. Canon EW-83E lens hood is the most important accessory for each lens you possess. The Canon EW-83E gives various functions: it shades the lens from stray light, enhancing your contrast and image quality; in inclement weather, it can help in keeping moisture or wind-blown debris off the lens. The Canon EW-83E hood can also guard the front barrel from the inevitable impacts against walls, door frames, and other real-life obstacles.
