The genuine Canon EW-88 lens hood is designed to prevent unwanted stray light from entering the lens. 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
• it protects the front barrel from the inevitable impacts against walls, door frames, and other real-life obstacles.
