Canon ES-65B Replacement Lens Hood

Act as a shade (visor) and prevents stray light from entering your lens, thus reducing glare and flare for better visibility and image quality. It also helps protect your lens. It adds an extra layer of protection to your front lens element. A must-have when your subject is backlit, you’re shooting into or near strong sources of light (like the sun), you’re using an off-camera flash that creates lens flare, or when you’re shooting near street lamps, cars with their lights on or buildings.
