Depending on how seriously you expect the extra wide lenses to perform you may want to consider a Sigma 12-24 as the solution. I have the original version & have read that the newer version is noticably better. (I'm quite happy with what I have).

I may be thinking of the wrong lens because the only Sigma 10-20mm I have had any experience with is a f4-5.6. Not a f3.5 version. So you have a lens I don't know anything about.
But the f4-5.6 is not a great lens and certainly not going to give the results a 1D X is capable of delivering.
But to each his own. Good luck with it.
