I have the Sigma 15mm fisheye, and I can get circular or rectangluar. If I remove the cap and collar, the image is rectangular. If I leave the collar in place, it's circular.
Sounds like a good lens to own Jerry. And at half the price of my Canon 14mm f/2.8 a better deal.
I also have the 8-15mm ultrawide to fisheye zoom which is the one I rarely use, but when I do, it works wonders.
It is also one of those lenses that is much too easy to over use (like fancy fonts in desktop publishing) -- less is decidedly more!
