Canon ET-73 Lens Hood for Canon EF 100mm F/2.8L Macro IS USM Lens - Compatible with DSLR Cameras, Perfect for Macro Photography & Outdoor Shooting

Canon ET-73 Lens Hood for the Canon EF 100mm F/2.8L Macro Lens. One of the most important accessories for each lens you own. A lens hood provides multiple functions: it shades the lens from stray light, improving your contrast and image quality; 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. Almost all EF and TS-E lenses have a Canon lens hood engineered specifically for it.
