Canon vs Sigma 10 - 22mm or other wide?

[Meysha]

Hi all,
Can anyone point me to a comprehensive review and comparison of the Canon and Sigma 10-22mm Lenses? or is there another lens I've forgotten to compare - i don't want to go tamron though.

I need to buy a wide angle lens for my landscapes and for my trip overseas.

Or if you have experience with both of these lenses could you give me your recommendation?

Most important for me is low Chromatic Abberations - I hate it with a vengence. Must be sharp - these have to be able to be blown up big - to A3 size maybe. Doesn't have to fit full frame (i have a 350D at the moment) - but that is a +ve as I have film too.

hmm i'm sure I'll think of more 'musts' but I really need to read a review of the two against each other.

Thanks!
Vicky

Oh also, I've read that the sigma 12-22 (?) is better... can anyone back that up?

I think it was Digital Photography magazine that recently awarded the Sigma 10-20 there best on test lens. (Or editors choice or whatever they call it).
