The Tokina is full 180' fish at 10mm but at 17mm it will be cropped, so you'll see more minor distortion, not unlike using a 35mm-designed fisheye (like the Zenitar) on a DSLR.so tokina 10-17 fisheye is a real fisheye at the 10 but would it be just "normal" at the 17 and canon 10-22 wouldn't be fish eye, just normal throughout?
For example, here's a Zenitar shot from my DSLR, this is probably pretty close to a Tokina 17mm shot.

Here's one (a repeat from the film shots earlier in the thread), first the DSLR version:

And the film version:

As for circular fisheyes, Sigma still makes an 8mm circular fisheye, but it is cropped on non-FF DSLRs, but I think you still get quite a bit of distortion even then.
