The main function of the lens hood is to shade the lens from stray light, improving your contrast and image quality. But it will also protects the front barrel from the inevitable impacts against walls, door frames, and other real-life obstacles and in inclement weather, it can assist in keeping moisture or wind-blown debris off the lens.

The advantage of the petal shape design is, that it offers the same prevention of flare as the corresponding circular or rectangular design, but with a smaller size and a lighter weight.

Installation:
