Many photographers use lens hoods when taking photographs. The lens hood helps block out the sun, which can cause an unwanted flare in what would have been a perfect shot. Canon makes lens hoods for almost all of its lenses, depending on the type and size of lens. The hoods are very easy to connect to the lens. This Nikon Flower Petal Lens Hood is high quality plastic, durable and light weight, protect lens from scratches, fits for most lens with front filter thread, and easy to use.
