ProMaster ET-74B Lens Hood for Canon
Using a lens hood prevents contrast killing, flare inducing side light from hitting the front lens element. Pictures taken with a lens hood will generally have richer colors and deeper saturation. Lens hoods also provide extra protection for your valuable optics. ProMaster replacement lens hoods are super high quality with excellent fit and finish.
