I dropped into Ted's yesterday to check up on battery and CF card prices (got both - 13% sale, yay for Friday the 13th), and checked out the Sigma 10-20mm lens while there.
These are not fantastic shots being inside a camera store after all, but they do show how wide the lens is.

Gotta love the distortion on that one.
I'm fairly impressed with the distortion control actually, esp for something so wide. But yes, ultra-wide lenses are great close up for that interesting distortion :)
