In addition, since the end of the lens is extended, you also get the added benefit of some extra protection from accidental impact.Dedicated lens hoods, such as the Canon EW-73B, are designed to match the specific focal length of the lens it was designed for. >> Compatible with the following Canon lenses: EF-S 17-85mm f/4-5.6 IS USM Lens

Customer Reviews

tight fit, bad fit
Although this claims to be from "precision design", the thread on the hood does not fit the thread on the lense well, and you need to twist it really hard to mount either forward or backward. It takes so much force that makes me worry that I'm gonna one day destroy my lense. On the other hand, I've never tried the original Canon hood coz it's twice as expensive. So anyone can give me some feed back on how the Canon hood fits would be appreciated.

Works great during the day.
When you use the pop up flash it cast a little shadow in the picture. So it Works well with the external flash! or you can just take it off.

Pretty good
This has been a pretty good lens hood for me, the only drawback has been that when I shoot at 17 mm (using my 17-85mm Canon lens) the hood sometimes shows up in the corner of my photos. Perhaps it's because I'm not using a full-frame camera (I have a Canon 40D) or I have screwed it up somehow but it is an occasional problem. The hood seems very well-made, though, definitely a higher-quality construction than some non-Canon hoods that I have.
