Unique Ultra-Wide Angle Lens But Poor Sigma Quality Control, July 3, 2006 By Amazon Verified Purchase This review is from: Sigma 12-24mm f/4.5-5.6 EX DG IF HSM Aspherical Ultra Wide Angle Zoom Lens for Canon SLR Cameras (Electronics) There's nothing else this wide for use on a full-frame 35mm camera or digital such as the Canon 5D. It's so wide on a full-frame that you can almost see behind you (well not quite, but close to 180 degree field of view). It is not a fisheye, so straight lines stay straight. There is some minor vignetting at 12mm but less than the Canon 17-40 L-lens I had at 17mm. This lens is pushing the limits of physics so it is not as sharp as some lenses but it takes in so much more of the view and provides a crisp image all the way to the corners.
For use on a cropped sensor camera, such as the XT, 20D or 30D a better choice may be the Canon 10-22mm which is uber-sharp in the middle of the frame. The Canon, however, gives fuzzy images on the sides when wide open but sharpens up when stopped down to f8 or more. My third copy of the Sigma lens is less sharp than the Canon in the center of the frame but is sharper starting about halfway to the edge when both lenses are wide open... Read more

Professional 12-24 lens, January 21, 2006 By Stopdown (Boston MA) - See all my reviews This review is from: Sigma 12-24mm f/4.5-5.6 EX DG IF HSM Aspherical Ultra Wide Angle Zoom Lens for Canon SLR Cameras (Electronics) I use this lens primarily for architectural work. It's rugged, fast focusing, and most important, distortion free (i.e., straight lines stay straight). Dramatic design, built for full frame use if (when) you decide it's time to go that way. It's also performed extremely well for landscapes....even some shots at weddings. My most frequently used lens. (Hint: on the APS-C format digital SLRS, you can leave the accessory ring on the lens - it provides additional flare resistance, and there is no vignetting.)
14 of 14 people found the following review helpful Impressive performance and value., July 21, 2008 By This review is from: Sigma 12-24mm f/4.5-5.6 EX DG IF HSM Aspherical Ultra Wide Angle Zoom Lens for Canon SLR Cameras (Electronics) I bought this lens to service a new client that does virtual tours for hotels and resorts. Their lens requirements are 18mm for full frame digital cameras and 12mm for DX chip cameras, to shoot 360 degree VRs. I didn't want to invest the 1000.00 plus dollars for another Canon lens and Canon or anyone else for that matter doesn't make a lens with this range. The Sigma would allow me to use both my 1Ds Mk II and 20D to service this client and cost me half what anything Canon provides.
Having bought the lens mainly for Internet content, I wasn't going to be too critical about image quality from it, but I've been very surpised and pleased by it's performance. This lens has the least amount of barrel distortion of any wide angle zoom lens I've ever used. Even less than some primary lenses. To the point where it is essentally undetectable to the naked eye. It has less barrel distortion than my 1000.00+ 24-70mm f2.8L Canon lens! Operation is smooth, fast and constructions... Read more
