I'm researching a new purchase for my Canon 30D and I'm already lost. Was looking at getting the Sigma 4.5mm 2.8 fisheye and discovered that there is a Sigma 8mm 3.5 fisheye. On B&H, both lens' are described as "a spherical fisheye lens that easily captures a full 180 degree view in all directions, in a circular image". So other than the obvious what's the diff? :dunno
Canon 30D & REB XT (thinking of converting to infrared), Sigma 10-20mm, Tammy 17-50mm 2.8, Canon 24-70mm 2.8, 70-200mm 2.8 IS, Tokina 100mm 2.8 Macro, Canon 50mm 1.8, Canon 1.4 ext, and Sigma 4.5 fish eye along with a Bogen by Gitzo Tripod, Manfrotto Ball Head, MacBook PRO, several HOYA filters and a 2GB & 8GB San Disk, 160GB Sanho storage device (really cool btw)......wishing for a Canon 100-400mm. :wink

The 8mm is made for a full frame body and if mounted on a 30D it would give you a image like this.

If you are looking for a circular fisheye, then the 4.5mm version would be for your body.
Thanks for clearing that up! Almost bought the wrong one!
just to be clear--the full frame lense can work for both. the crop lens can only work on a crop body.
