Canon 10D + Canon 2.8/15 Fish. It seems to be a good possibility to get real wideangle effects in cases you want to show small plants within their natural surrounding.

H. Kretzschmar, Beautiful images, Shows that the 1.6 crop can go wide! I see Sigma also make a 15 mm fisheye. Have you heard of any positives or negatives regarding this lense? Erin
I just got the Sigma and it's very sharp. I did some research and heard that there is a little sample variation, but if you get a good one it's really good. I think I got a good one.
The focus is a little slow, but the same is probably true with the Canon as neither are USM/HSM
I have this lens and I love it. You can do landscape photos that don't show the fisheye effect, but you usually will want to crop some of the ends off, or just live with the 'cool' effect. If you adjust the horizon to be in the middle of the shot, the fisheye effect is minimized. But this isn't always possible.
If you want to really see the power of the lens, put it on a camera without the 1.6 crop. I use this lens on my film EOS camera about twice as much as I do on the 10D. I found the angle of view on the EOS is about 180 degrees. On the 10D it's about 90, so you're missing the lens' full power here.
On the 10D remains 114°, yet much more then any other lens has. I don't know the Sigma 15 mm fish, some investigators like photonet say it may be not as good as the Canon.
At now on the 10D the combination of the fish with the 2.8/24 is my common wideangle equipement. Performance of this combination of 2 "tiny" lenses is no doubt better then that of the bulky Sigma 15-30 mm.
One piece of free software everyone recommends for defishing a picture is PanoTools. It can also be used to stitch together a panorama from a number of shots. However, the PanoTools website (http://www.fh-furtwangen.de/~dersch/) is "closed" til Sept 20!! Does anyone have a recent version they can post or email? It's freeware, so don't be shy
FWIW, I tried out my brand new Sigma 15 fish last night and I'm very impressed (and pleasantly surpirsed) at the image quality. It looks to me like it could be a legitimate option to the Canon. Here're a couple of examples:
Joe: Re the Sigma 15 v the Canon comparison -- I expect you are probably correct in terms of resolution, but the Sigma has a notably yellower color cast to it than the Canon. Not that that's bad, just different than most other Canon lenses.
