The Canon EW-83L Lens Hood is black in color and sports a petal-like design that gives you protection against stray light, which is a major cause of unwanted lens flare. This Canon hood gives you maximum coverage without intruding into the camera frame. It also offers you some amount of protection against physical damage and accidental impacts. The lens hood attaches with two pronged Bayonet mounts. It also has its own locking mechanism. The inner surface of the hood has been given a special flocking treatment that offers excellent anti reflective performance.
