Help Prevent flares
Designed for 17-85mm f/4-5.6 IS EF-S and 18-135mm f/3.5-5.6 IS Lenses
Imported from USA
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. 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. Canon's EW-73B Lens Hood is designed for the
Canon EF-S 17-85 f/4-5.6 IS USM SLR Lens.
