Product Description
Canon EW-73B Lens Hood For 17-85mm f/4-5.6 IS EF-S and 18-135mm f/3.5-5.6 IS Lenses. The addition of a lens hood can help prevent flares--those circles of light that can accompany images where a strong light source is just outside the fame. Canon's EW-73B Lens Hood is designed for the Canon EF-S 17-85 f/4-5. These type of lens flares occur when indirect light rays pass through the front lens elements but don't make it all the way through to the image sensor.
