First up let me say that I am not a professional photographer or even a very experienced amateur. I might not know all there is to know about photography but what I do know is that I LOVE what comes through this lens.
I was pleased with the build quality (as I have been with all my Sigma EX series lenses) and initial testing showed the autofocus to be fast, accurate and VERY quiet. This might not be surprising to those of you with a bag full of Canon L USM lenses but coming from consumer grade lenses this was a revelation.
I was seriously taken aback by just how wide 10mm is on a 1.6 crop camera (Such as Canons xxD and xxxD ranges). I could stand almost on top of subjects and still manage to get them all in. The extreme angles involved creates some distortion effects but these add to the pictures in my opinion.
The real joy however was when I returned from my first outing and began sorting through the pictures. The colours were fantastic, the images were, without exception, very sharp and the creative possibilities on a lens this wide made the photos stand out far more than the usual "snapshots" that a photographer of my calibre produces.
The ultra wide zoom made by Canon may well be better and I've no doubt that a full frame camera with professional grade lenses might yield better results but for this price I cannot find fault with Sigma's offering.

Anyone looking at this will know the technical stuff so i'm not going to bother with that!
I bought this for a trip to San Fracisco, Yosemite & the Grand Canyon. I am so glad I did. It is a fantastic lens, quick, responsive, quiet and above all the photos are sharp!
At it's widest setting there is a a good deal of vignetting if the lighting isn't spot on, but once you get used to it, it's fairly easy to overcome. I am using it on a Canon 350d and have been really impressed with the results.
I have had a canvas made from a photo of the Golden Gate bridge at sunrise and a photo at sunset taken at Rossnowlagh beach in Donegal, Ireland.
I would recommend purchasing the Sigma EX 77mm circular polarising filter as it works wonders on this lens.
The picture in the gallery was taken mid afternoon (not always the best for photos) at 10mm, F/9, 1/200sec.

I'm a pretty well seasoned photographer type but a bit a few hours spent with this lens has convinced me that I needed one of these lenses immediately.
This is one of their Sigma EX range which according to the bumf means it's better engineered, better built, higher quality materials, at least on the outside, and to be fair that's about right. The focus ring is not too loose, not too tight, the motor is quick and quiet and it's all finished in a nice kind of grippy tactile stuff. It's got a good solid metal mount but as expected it is fairly weighty lump when bolted to the camera, but not in a bad way, just solid and well balanced.
It's internally focussing which is good. Because the lens is physically fairly short no outside part of the lens will spin wildly in your hands when focussing, all the spinny bits are inside so it turns out to be a bit of a joy to handle.
Probably best to note right now this is a superwide lens so look elsewhere if you're after something other than this. However, the depth of field on this thing is enormous so watch out of you'll be noting the accidental inclusion of your feet in many snaps. For the right application though, this lens is a stormer. I've used it for some stunning travel shots, big moody sky landscapes, funky nightclub shots and portraiture snaps with a fun exaggerated perspective. You can pull off some very funky modern photography techniques very easily with this one.
Results are great, err spectacularly wide, sharp (far outer edges are less so but it is superwide so that's expected), well controlled aberration and no obvious loss of colour. All very good and a bargain price. I also looked at the Canon and Tamron equivalents. The Tamron cost a bit less, was lighter but felt a bit cheap and plasticy in terms of build quality. I couldn't fault the Canon other than its more offensive price.
I'm now a happy Sigma convert. I can also recommend the Sigma 18-200mm DC OS if you're after a big image stabiliser zoom too.
Anything else, umm, yes, it's an uncomfortably large glass area to damage at the front so make sure you grab yourself a 77mm UV filter. That'll protect it and is easier to swallow financially than the cost of a new front element repair. About £25-30 high street of £10 to you sir from Ebay.
Anyway's - Sigma 10-20mm is recommended.

Not perfect - usual Sigma issues.
For the money this lens is okay but from the very beginning I've had sharpness issues with it. I sent it back to sigma because it wouldn't focus sharply across the frame. Read more
