ProOptic ProOPTIC Lens Hood for Canon 70-200mm f/2.8

Protects your images from ghosting and unwanted flare, while also protecting your lens element from impact and abrasion damage. This is a dedicated lens hood for the Canon 70-200mm f/2.8 IS (type ET-86). Using a lens hood specifically designed for your lens provides the benefit of creating the maximum amount of shade and flare protection without cutting into the picture. Using a lens without a hood will often result in white or colored spots on an image (flare), lack of sharpness, and an overall bleached look to your image (ghosting) caused by unwanted light entering and bouncing around inside your lens. Additionally, a lens hood creates a buffer space between the lens's delicate glass elements and any objects that could scratch or damage the glass.
