I am thinking about getting a Sigma 4.5mm f/2.8 EX DC circular fisheye for Canon ASP-C sensors, mainly for taking all-sky astro-images.

I don't think it's the best fisheye out there for that kind of shots though.
I've used this lens on a 1Ds3... a few of the 45 AF points even fall outside the image circle from what I remember.
