well i f'd up and bought a canon 10-22 lens which i found out doesn't work without modifications to lens on my camera, so searching around i found a Tokina 11-16mm 2.8 and sigma 10-22 or 12-24.
does anyone know if the 11-16 or 10-22 sigma work with the apc-h sensor cameras?

If you need such an extreme FL the Sigma 12-24mm is the best (and only?) option for you.
+1, Only true UWA option for APS-H that works through the entire zoom range. Will work on full frame too... I can verify that the Sigma 10-20 will vignette heavily on the wider end of the zoom.
I've been researching the Tokina 11-16 for use on the APS-H 1DIII and from what other users here have reported, it will work without vignetting from around 12-13mm. It's not ideal, and I guess essentially does what the Sigma does out of the box, but is still an alternative solution.
I'm actually about this close *holds fingers up* to buying a Tokina 11-16 JUST to use it at 16mm on a 5D.. It's a fine lens by any measure.
I also have an inkling I may end up with a DX backup body in the near future so it would be ace for a wide on that
Depending on your zoom range requirements the Tokina could also be a viable alternative - 1.3x crop would cut out the iffy wide-open corners on FF and give you a very sharp ultra-wide which can be used at f2.8 in a pich for a nice price. Only thing is you would be limited to say 13mm-16mm zoom. BUT, many people use their ulra-wide zooms at only the widest seting and the longest setting and rarely make any stops inbetween.
Still, the Sig 12-24 is nice lens and far more versatile. I just wanted to throw pinch of salt in the discussion here
The lens is easily modified to allow use on 1.3x crop EF-Mount bodies such as the 1D Mk III by removing the snap-in rear plastic piece. The same modification allows the lens to mount on full-frame bodies such as the 5D, although the rear of the lens contacts the mirror at wider focal lengths.[7]
I've heard that the mirror-contact issue is not a problem, so long as you don't use the 10-12mm range
