I have been taking some mountainbike photos lately and would like a wider lens for my Digital Rebel. Would the following be a good choice? Canon EF 24-85mm f/3.5-4.5 Ultrawide Zoom Lens

Any comments or suggestions would be welcome. Thanks.

Well I've already figured out that is not the lens I need. I want something with a much shorter focal length, maybe even a fisheye.

I use the EFS10-22, a very nice wide lens suited to the rebel.
Works well on my 20D too.
