Summary: Great wide angle!
Comment: I bought this lens because it was cheaper than the Canon version, and won an award in europe for the best consumer lens of it's kind. I use it with my Canon 30D digital SLR. It's very sharp, and feels great when shooting. Great Wide angle is you don't have one. Please note that this lens will ONLY work with a corresponding DIGITAL SLR.

Summary: fantastic
Comment: This is my first "real lens". the Sigma EX line is a good place to start getting into quality glass. I was looking for something of a fisheye (maybe not that extreme) but definitely something wiiiiide.
This fits the bill very well. It is not the most extreme angle but it really captures depth/space in the frame and creates an interesting look. You'll learn to be aware of your entire environment as the wide angle can capture things on the extreme periphery. It makes scenes more lively, i had my sister shoot with this lens at a wedding reception with some very entertaining results.
Only concern is that this is an f4 lens compared to Canon's L series wide lenses that hover around f2.8. But then you'll spend over twice as much!

Summary: Nice price for a great lens
Comment: Sigma continues to impress me. My one pricey Canon-brand lens (28-70 f/2.8 L) has color-fringe problems, and my two Sigmas (this one and the very sweet APO 70-200 f/2.8 EX DG HSM) are dead-on correct and free of chromatic aberration. My chief complaints about this lens are fairly irrelevant since they center around its inherent design:
1) variable aperture (makes you have to change your flash settings if you shoot manual)
2) it's not a f/2.8 lens
I was aware of these design specifications (not issues or surprises) before buying and am pleased with it despite them. That's the tradeoff you get for a great price.
It's nice to have a true wide-angle lens back in my arsenal, since the 28-70 combines with my 1.6x sensor size factor to become a 45-112, hardly wide.
To anyone considering buying the lens, just be aware that it's not for full-frame cameras. If you don't know what this means, or aren't sure what yours is, read the manual.
The field of view is an immense 102° side-to-side, and it focuses down to about 6" from the subject at 10mm.

Summary: Overall, a great value.
Comment: I bought this instead of the Canon 10-22, and never looked back. Reviews seemed to indicate they were fairly comparable, with no clear "winner" in Amazon user reviews or in the trades, but I was on a strict budget and had 2 lenses to buy: this was the one that went cheap.
In use it is very good. When wide open at the 10mm end there's vignetting and some chromatic aberration is visible (the dreaded "purple fringe" variety) at wide apertures. Start tightening up the view, though, and it gets much better pretty quick, say by about 12mm@f/8.
At the 20MM end it is sharp, clean, and lovely. I've done portraits with it - pretty pleased with the outcomes.
But what I bought it for was that big, nasty 10mm wide angle barrel distortion thing, and shooting hand held outdoors in low light or straight into the sunset at 10mm with the aperture at f/22 or so it is just great.
I only saved a few hundred bucks, but no buyer's remorse here. None of the complaints about short focusing soft spots or bad workmanship for me.
Highly recommended.
