Amazon.com Product Description
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.

Customer Reviews

Useful shade
This shade, made by Canon is much better, a better fit and more sturdy than a generic shade sold by a famous NYC store. It is well worth the price, and does not interfere with the use of filters.

Don't get it for the Canon EF 10-22mm Lens
My mistake obviously, but I took some erroneous online advice to use it for my Canon EF 10-22 lens and it doesn't fit at all. Even if I monkeyed with it there's no way it would fit.
I still gave it 4 stars because it's a nice quality piece. Minus 1 star because they weren't clear about the size of it.

Good lens hood with one limitation
This lens hood does what it's supposed to do, but if you are using a 40D with the built in flash, it will cast a shadow on your subject at about 28mm and within roughly 7 feet.
