After intensiv testing Canon's and Sigma's fish - in diffrent light situations - I went for the Sigma, as it showed better results on a 10 D. CA was bigger on the Canons fish, the Sigma has it too, but less expressed. CA depends much on light situation, but I'm not really able to tell when CA will occure. As this is my first and only Sigma lens - and I will not go for other ones, I was positivly surprised. Even after defishing, some 30/20 cm/300dpi files look good.
My others: 17-40, 50 mm macro, 100 mm macro.

Superb optics

AF gets confused
|
|

Optically this lens is a champ. I am no optics engineer, perhaps designing a fisheye isn't that hard after all... because this one simply in another league with similar rectangular lenses I've tried: not only it's f2.8 (being relatively compact), but it's tack-sharp @2.8! Even flare isn't much of a problem. Colors, contrast, sharpness - everything is great.
However at such wide angle 10D's autofocus gets confused. Actually this lens can't AF on anything beyond 2-3 meters. But with such huge DOF I usually just set it somewere between 1m and infinity, and everything is in focus, even at f2.8.
Also I noticed that my 10D tends to overexposure about one stop with this lens. Not sure if it's a wide angle issue. I haven't used anything wider than 17mm rectangular, so I can't be sure.

Pros:
|
works perfect with Canon 10D, very sharp even wide open, smooth focussing
|
|
Cons:
|
very little flare, fisheye distortion has to be corrected with software.

This lens is the perfect solution for anybody who looks for a real wide angle lens for APS sized DSLRs. For theese cameras it's like a 20mm for analog ones. The image quality is really incredible, stopping down is only neccessary to reduce light. Particular at night it delivers pinpoint start from edge to edge and full contrast.
The typical fisheye distortion is no problem, it can be corrected with software or accepted, if the image contains no or very little straight lines. For star constellations the distortion is an advantage.

Pros:
|
Good solid build, very good color and contrast, extremely sharp for an ultra wide of this type, quite fast auto focus performance.
|
|
Cons:
|
slightly soft on left and right hand sides of frame wide open, can't take front filters, so you need to be careful of the front element, especially shooting close to subjects, as its easy to loose perspective of how close you are to objects.

I had tried the Canon EF15 Fisheye prior to this purchase, and both the Canon and Sigma produced similar results, both show slight Chromatic Abberations on L/H & R/H sides of frame, but no worse than the highly respected sigma 15-30, or the Canon 16-35L.
I use it on a 10D which doesn't quite yield a full fisheye effect, but does give you an exceptionally wide view, that can be perspectively corrected with software tools to simulate a rectilinear wide lens.
Overall excellent performance at a much lower price than the Canon. This is the first and only Sigma lens I have owned, so I was sceptical, but after getting it very pleased with the quality.
