Review summary from DPReview
Overall the Sigma 10-20mm F4-5.6 EX DC HSM is a solid, well-built lens with good operational characteristics, which justifies its popularity with generally decent imaging results. While its long-running, unique selling point of being the only third-party 10mm zoom has now disappeared, and it faces strong competition from Tamron's 10-24mm, the different characteristics of the two lenses means it's still a good option for APS-C users looking for the widest of ultra-wideangle zooms.
Scoring is relative only to the other products in the same category.

Sample images for Sigma 10-20mm F4-5.6 EX DC HSM
Designed exclusively for Minolta and Sony 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. 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
The lens incorporates an internal focusing system that eliminates front lens rotation, letting you use a petal-type hood to protect from additional glare.
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.

I had planned to buy the 12-24mm Nikon next Spring when my budget would allow the expenditure. I have had success with Nikon optics in the past - starting with my first Nikon FM back in the seventies. The Sigma's good construction, nice finish, smooth+fast+quiet focusing and 10mm focal length convinced me to try my first non-Nikon lens in 30 years. A big factor: The Sigma lens is less than half the price of the Nikon lens here is Canada. It fit my budget, so I took the plunge.
The Sigma fits into my "sharp enough" category. In real world shooting, its sharpness is on par with my 18-200mm Nikon. Both lens are less sharp than my $100 50mm 1.8 when "test" images are blown up to 16"x20" size. I never notice any lack of sharpness in "real" pictures. I care more about color saturation, contrast and color balance anyway. In this area, the Sigma does well. Saturation and contrast are equal to both my other Nikon lens - particularly at f8 and smaller aperatures. Wide open, I find some weakening in contrast. The Sigma has a warmer color termperature than my other lens. One click toward blue in Photoshop would fix this minor variance in color. But I use my 10-20mm almost exclusively for landscapes. The warmer color is generally a good thing.
I have noticed some vignetting @ 10mm f4. Zooming to 12mm or stopping down to f5.6 elminates any artifacts in pictures I have taken thus far.Read more ›
When I received my lens I later realized that I did not receive the extended three year warranty card that comes with the USA versions of the lens. Instead of just sending me the extended warranty card Amazon shipped me a whole new lens. Now while I was reading reviews prior to ordering this lens I had seen many reviews where the reviewer either loved this lens or they hated it. After a while I could see why...
Some of the lenses that are being shipped are sharp all the way around while some are not sharp at all. Many claimed it was sharper at F:8 than F:4 while others said theirs was never sharp at all. Some complained about distortion and or dull or over saturated colors. I finally found a reviewer who had the opportunity to try 3-4 different lenses. They found that there seemed to be a lack of quality control all around when it came to this specific lens. Having a few days of both lenses I decided to compare them out for myself. I am glad I did.
I put my camera in the front yard on a tripod and shot numerous sets of three for each lens at 10mm, 14mm, and 20mm. The results were surprising. The original lens I had been sent first was a clear winner. The trees and anything else around the picture were sharp, The replacement lens was anything but sharp. The colors on lens two were more vibrant than lens one but one can fix that with software where a blurred image is not really fixable.
I shot numerous sets with both lenses and a few different F settings and the results remained the same. The replacement lens was the one being returned.Read more ›
1. Packaging - Came in a very attractive box with a manual and included not only a lens hood, but a very nice lens case! Good Job Sigma!
2. Build - The lens feels tough and has a very attractive finish to it. The focus ring is nicely dampened and is very easy to modulate. My only gripe is that the lens cap is useless, get a nikon lens cap and youre all set.
3. Performance - The sigma is 2mm wider than its nikon and tokina counterparts and boy does it make a difference. The FOV is wide on my D50 and i can capture so much on one single shot that when people see them, their first words are "how the hell...". Distortion at the wide end is there, but is easily controllable through precise leveling or from post processing. You might see some vignetting at 10mm but just stop it down and you should be all set (or you can correct it with a click of the mouse in photoshop). I have heard complaints about sigma not having a constant aperture. In my opinion, who the hell needs it. When I am taking shots in the day, the natural light is sufficient enough. For night shots, i use a tripod and usually stop it down to F8-f10 where the sigma's optical performance is at its best. This is an amazing piece of glass and I encourage those looking for a wide angle lens to definintely take the sigma into consideration. Looking at Sigma's future lens lineup, I don't consider them to be a 'third party' lens company anymore. Sigma will definitely be considered on my next purchase for a telephoto lens.
