And no vignetting will be caused with the hood on when you are shooting. In addition, the "petal" shape of this lens hood maximizes the amount of hood coverage for the minimum amount of weight and hood area. Since the end of the lens is extended, you also get the added benefit of some extra protection from accidental impact.JJC LH-JDC100 lens hood replaces Canon LH-DC100 & FA-DC67B.
