Dedicated to the Canon EF-S 17-55mm f/2.8 IS USM lens, the EW-83J Lens Hood helps to minimise flare by deflecting stray light from entering the lens. The hood also provides additional protection to the lens from accidental impacts, bumps, or scratching.

The "petal" shape of The EW-83J Lens Hood maximizes the amount of hood coverage for the minimum amount of weight and hood area. This dedicated lens hood is designed to match the specific focal length of the lens it was designed for.
