Amazon.com Product Description
Designed exclusively for Canon digital SLR cameras, the ultra-wide-angle 10-20mm offers a view from 102.4 to 63.8 degrees, making it ideal for landscape photography and other vast applications. The lens is distinguished by its three special low dispersion (SLD) glass elements, which effectively compensate for color aberration, and its aspherical lenses, which provide maximum correction for distortion and various aberrations. As a result, the lens produces an extremely high image quality throughout the entire zoom range. The HSM-equipped models, meanwhile, produce fast autofocus (AF) speeds and quiet shooting while still letting you perform full-time manual focus. Other details include a minimum focusing distance of 9.4 inches at all focal lengths and an integral petal-type hood to block out extraneous light. Lens Elements and Coating
The new multilayer lens coating and lens design reduce flare and ghost--a common problem with digital cameras--while also creating an optimal color balance throughout the entire zoom range. At the same time, the lens offers three SLD glass elements that effectively compensate for color aberration, along with a piece of glass mold and two hybrid aspherical lenses that offer excellent correction for distortion and all types of aberration. Inner Focusing System and HSM
The lens incorporates an internal focusing system that eliminates front lens rotation, letting you use a petal-type hood to protect from additional glare. And models equipped with a Hyper-Sonic Motor (HSM) produce silent, high-speed autofocus and full-time manual focus for Sigma, Canon, and Nikon D-mount lenses. Best Consumer Lens
The Sigma 10-20mm lens is so respected that it was named the best consumer lens in Europe (2006) by the Technical Image Press Association (TIPA), a collection of 31 publications from 12 countries. According to TIPA, the 10-20mm lens offers a versatile range of wide-angle focal lengths, a good optical performance, and a budget price, making it an excellent investment for owners of DSLRs with APS-C format sensors. Its sharpness remains constant throughout the zoom range, and its compact size makes it an ideal companion for shooting travel, landscapes, or architectural subjects. - Lens construction: 14 elements in 10 groups

 Fantastic! August 12, 2010

I have a Nikon D90 with the 18-105mm kit lens. The 18-105mm was adequate for most applications but for indoors and wide-open landscape pics, it can be a challenge. So, I started researching on wider angle than 18mm. With a budget of around $500, it came down to this Sigma, Tokina 11-16mm and Tamron 10-24mm. Based solely on the reviews here in amazon.com and a couple of other reputable online stores, I quickly ruled out the Tamron. Back then, the Tokina was $200 more than the Sigma (now I'm seeing a store listing it for $599). The Tokina is a f2.8 - very tempting offer but for me, I forsee most of my applications requiring both width and DEPTH, so f2.8 is nice to have but not a real deal-breaker.
The Sigma has the 10mm and 17-20mm range advantage over the Tokina's 11-16mm. Eventhough there were a few reviews about bad copies of Sigma, I went ahead and bought one, knowing I can always exchange it until I get a good copy. I bought mine here(but not sold by amazon.com - it was 47th St Photo).
I can say I am very impressed with the build, material and image qualities of my Sigma. In fact, all 3 qualities were better than my Nikkor 18-105mm kit and to be fair in my comparisions, all pics were taken in the 18-20mm range on both the Sigma and Nikkor.
I highly recommend this Sigma.

Mechanically well constructed. Come with pinch-type lens cap and hood, as well as boxy carrying case you can thread onto a belt or rigging.
I wasn't going to spend extra money for the Canon glass since I anticipate using this lens only occasionally. I figured I'd go with the Sigma over the Tamron because the Tamron is a 77 mm filter while the Sigma shares a 72 mm filter with my main everyday lens. I fully read the review on dpreview about the lens' performance at various apertures, but I wasn't prepared for how soft the picture looked at 10mm F4! Don't rush to return your lens if you're surprised by the poor quality of the test shot, try F11 or F13 where the lens performs the best. This does mean that I'll have to be more thoughtful capturing a landscape than just setting the aperture to F22 and firing away. No quality problems in my copy when stopped down, unlike other mentions here.

This lens is amazing, strong, durable, and makes some awesome picture. I am an amateur photographer and bought this lens for a trip to Wyoming. I have a Nikon D60 but it is a beast and this lens makes my pictures look professional. I have taken some amazing pics of Yellowstone, Devils Tower, and the mountains of Wyoming. The quality of the picture sometimes lacks, but nothing that can't be fixed by photoshop or lightroom and for less than 500 bucks it is one cheapest and best wide angles you can get. You can also take some very interesting close up pics (for example I take close ups pics of my pets) with this lens but you have to have an external flash.
I say this lens is durable because it has been dropped twice. Once on the concrete path at Devils Tower, it got knocked out of my coat pocket while changing lens and the second time got knocked of the car seat and then stepped on by somebody that wasn't paying attention and the filter got smashed into a million pieces. So to say the least it has been through a lot. but it still works perfectly which is a miracle in itself.
If you are like me and don't have much money and want a wide angle lens this is a the way to go and you will not be disappointed. I recommend you buy it a filter for protection (Zeikos sells a 77mm for 8 bucks and it is what saved my lens) and it comes with it's own case so keep it in it's case when not in use.
Bought this lens used from Amazon Warehouse Deals July 9, 2010

After spending countless hours reviewing the various UWA lenses, I settled on this Sigma 10-20mm lens. It isn't the fastest wide angle out there, but it is the only one at 10mm focal length at it's widest setting. After all, If you are going to buy a wide angle lens, why not buy the widest available (yet still affordable). I paid extra for next day shipping and the lens arrived promptly at 2:00 pm the next day. Although this is an Amazon purchase, I found the copy I bought from Amazon Warehouse deals, sold as a USED lens. The price was $80 less than brand new so I figured I'd give it a try, knowing that I could always return it if it was not in good shape.
When the package arrived, I expected to open the box and see a used lens wrapped in paper or bubble wrap. I was surprised to find that the lens came in the original box with original warranty card still in place. But best of all, this lens appeared to be new in every way. There were a few fingerprints on the front element which I took care of with a lens tissue, but other than that, there was not so much as a hint of wear or handling issues.
But the real test is how this lens works (or not works). I put it on my D90 and it instantly recognized the lens and was ready to go.
So far, I have taken about a hundred test images to be sure I got a good copy of this lens. I was particularly impressed when i took a picture of the front of my wife's Ford Escape at 10mm and about 6 feet away. After bringing the image into my PC, The photo was tack sharp but the real surprise was that I could read the serial number on the small decals of her license plate as if I had used my sharpest Nikon fixed focal length lens.
I am so pleased that Amazon's warehouse Deals had this (used?) lens for sale the day I decided to purchase one. If I didn't know better, and if there had not been finger prints on the front element when I opened the box, I would have sworn that this lens was brand new.
Great job Amazon.

 Crap! Go with Canon or Tokina July 4, 2010

I bought this lens never was happy with the results. Not very sharp and to much distortion. Very nice wide angle, but I did not feel the optics were very good. Recently purchased the Tokina 12-24 and could not be more happy! Only thing better would either be the Canon 10-22 or the Tokina 11-16. Save you money and buy one of these. I use my wide angle more then my kit, and it is worth investing in.
