What about the Tamron 10-24? I took a few pics with this lens from my friends...it is performing really good And it is a lot cheaper!

10mm iso 400 f7.1 1/320 canon 50D straight out of the camera, no postprocessing whatsoever.


Dpreview did a review on it... might be worth it...


The lens is a lot cheaper and in my view...the canon 10-22 is almost as expensive as my 17-55 is usm, but I'm sure the 17-55 will pay back sooner then the 10-22 will. Depending on the amount of shots you make with it.
