Canon Lens Hood EW-73B for EF-S f/17-85

Canon Lens Hood EW-73B for EF-S f/17-85

The utilization of a lens hood can aid in prevention of lens flare--the circles or streaks of light that can plague images in which a strong source of light is just beyond the perimeter of the captured image. These lens flares occur when indirect light rays pass through the objective lens elements at an angle that prohibits them from reaching the film or CCD sensor. Canon's EW-73B Lens Hood is designed for the Canon EF-S 17-85 f/4-5.6 IS USM SLR Lens.
