In summary, I find it interesting that very little good (and quite a bit bad) has been said about the Tamron 11-18. People are generally positive on the Sigma 10-20 and I hear audible gushing on the Canon 10-22 and Tokina 12-24. This is exactly why I find these discussions useful... thanks to everyone who has generously shared their impressions thus far.
One thing to keep in mind about the Sigma 10-20mm. There is quite a bit of distortion. But I like it, coz it is different. But when you don't want the distortion, you better carry a latter with you.

P.s., sorry, I can't spell today, my mind is not thinking right.

Tony,
Why do you think there is a lot of distortion in the Sigma. Here are my boring brick walls again at 10 and 20 mm. I don't think there is much distortion even at 10mm except in the extreme corners.
Tom, the sigma's distortion is said to be worse because it is "wavy". A "moustache" distortion I think it is called. It is harder to correct (if needed), in post proccess.
Tom, if you look at the 10mm carefully, it is almost a fish eyes effect. If compare to other wide angle, the Sigma one is pretty distorted. However, it does focus fast, even in extreme low light.
Ya'll know a lot more about the lens than I do and I haven't shot a lot with it yet. But, so far, I love it. Will upload DC picts next week and we'll compare.
Tokina 12-24 on sale at bhphoto, type "psjan" in search box and go to page 7, 434.95+Shipping, just got mine, new! I love the build and the contrast of the images. Clutch manual focus was very weird at first, but used to it now.
I went with the Canon 10-22, and my initial impression was not great... since then (I've learned how to use it) I'm really amazed. If I can stay away from f/3.5, my corners look awesome..
Everything else, color, contrast, etc are all top notch.

I agree, it looks like the wall is about to explode, but...it can be a useful effect too.
We'd review it if there was a place for reviews of this lens here on FM. I've given informal reviews in about 10 posts, but they aren't easy to access.
His evil mojo worked. I'm very happy with the lens.
