A dedicated lens hood helps to minimize flare by deflecting stray light from entering the lens. The hood also provides additional protection to the lens from accidental impacts, bumps, or scratching.</br> </br> Attention: There are a few Canon 18-55mm lenses, this lens hood replaces the Canon EW-60C lens hood and is only for the Canon EF-S 18-55mm f/3.5-5.6 IS II, which is sold as a kit lens on the Canon EOS 2000D 1300D 1200D Rebel T7 T6 T5 T4i T3i T2i DSLR camera. So it does not work with the Canon EF-S 18-55mm f/3.5-5.6 IS STM or the Canon EF-S 18-55mm f/4-5.6 IS STM, which is sold as a kit lens on the Canon EOS Rebel T8i T7i T6i T5i SL3 SL2 SL1 EOS 90D 80D 70D 77D DSLR camera.</br> </br> Easy to use bayonet mount attaches to your lens for a tight and secure fit. Just twist on or off. No wobbling or cross-threading. Handy reversible design allows you to attach the hood in reverse for easy storage in your bag.
