I got the sigma 8-16 and was really happy with it. I'm sure the canon is sharper and the tokina is faster. But since the DOF is basically infinite at wide angle anyways I personally don't see the point of fast super-wide angles. Since you
re shooting wide angle you can use sick (long) shutter speeds and get sharp images anyways. That said I'm sure all 3 are good options.
