If the 1Dx can fit the sigma 8-16mm it might be the solution.

In what sense? The Sigma 8-16 is an f/4.5-5.6 on APS-C. That is like using a f/6.7-f/8.4 on FF. It gets nowhere near the f/2.8-f/4 you say you always use.

There is an argument to be made that the Sigma 8-16 mm is one of the best UA wide-angle lenses (at the apertures/DOF that it offers) possibly the best in terms of performance vs. price. But the best way to profit from that is a crop camera, the latest Sony APS-C sensors are so good at base ISO, that pairing them with the Sigma gives you quite a lot of bang for the buck.

5. If you really like the Sigma 8-16, then it's best used on a APS-C camera, Nikon or Canon as you choose. If you want the same AOV on FF, Nikon has the 12-24/2.8 which is a superb lens and nearly 3 stops faster taking into account the crop. If that's too expensive, Tokina does a 12-24, which is apparently quite good.


the Tokina 12-24 is an APS-C lens (but a pretty good one), there is a Sigma 12-24 mm FF lens but it is not quite as good as either the Tokina or the Sigma 8-16 mm.
