The crop factor doesn't exactly translate to a "change in focal length" on a fish eye. However it still may be useful to you, especially once you defish the image - though that can lose you quite alot of coverage with these lenses.
The following page (not mine) has images from a Sigma 8mm on a Canon 10D, and they give a good idea of the image you'd get.

I hope that helps.
I'm interested in the Canon 15mm full frame fish eye for wideangle on my D30. The images people have been getting with it look great, even without defishing (the crop removes most of the badly distorted area, while the lens is wide enough to give the coverage I want.
Unfortunately I have to wait for my finances to recharge after the housing.
