Product Description
10-20mm F4-5.6 EX DC HSM lens allows enjoyment of super wide-angle photography and it is a very powerful tool for indoor shooting and landscape photography with digital SLR cameras. Wide angle of view (102.4 degrees at 10mm and 63.8 degrees at 20mm) offers the photographer greater freedom of expression. 3 Special Low Dispersion (SLD) glass elements are employed for effective compensation of color aberration, which is a common problem with super-wide angle lenses. One piece of glass mold and two hybrid aspherical lenses, offer excellent correction for distortion, as well as all types of aberration. This lens is equipped with an inner focusing system, and the models which are equipped with HSM system provide quiet, high speed autofocus shooting and also offer full time manual focusing. It has a minimum focusing distance of 24cm at all focal lengths. The non-rotating lens barrel perfectly suits the petal shaped lens hood. A circular polarizing filter can also be used conveniently. Angle of View - 102.4 - 63.8 degrees 6 Diaphragm Blades Minimum Aperture F22 Minimum Focusing Distance - 24cm/9.4 inches Maximum Magnification - 1 - 6.7 Filter Size - Diameter 77mm Lens Hood Petal Hood Dimensions - Diameter 83.5mm x Length 81mm, 3.3 x 3.2 inches Weight - 470 gram (16.6 ounces)
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

 Excellent Value - Good Quality January 6, 2009
T. Schulz (Midwest)
This is my first non-Canon lens purchase. I currently own two Canon lens for my 40D body, the Canon 70-200 f4L and the 17-85 which have excellent in their results.
I am very pleased with this Sigma 10-20 Ultrawide lens. The build quality is solid, my prints look very good, and the price is best in its class. The color and sharpness have been excellent. I would highly recommend this lens to anyone looking for an Ultrawide for their Canon DSLR 1.6 camera.
 Sigma Disappointed Me Again December 31, 2008

You get what you pay for. Got this as a Christmas gift for my wife who used it for the first time yesterday for our daughter's 13th birthday. It was discovered that a shadow was present in all the pictures taken with this lens, starting from bottom center as if the hood cover was getting in the way, yet the shadow was there with or without the hood... then we noticed the dark picture when the lens was at full 10mm. I knew there was a hit and miss with this lens before I bought it, but now I wish I would of spent the extra $200.00 for a Canon.
Fantastic! November 12, 2008

This lens is great! I got it for under $200 because it was open-box, so I'm extra lucky. :-)
A lot of people have been complaining about the sharpness, but mine at least is perfectly fine everywhere. Note that the aperture is somewhat low, so you may need a flash (and the pop-up won't do because of lens shadow). Otherwise you may need to stay outside. Keep that in mind when you buy it, but that shouldn't really confine you too much.
Also know that the image will of course be somewhat distorted due to the wide-angle.
overall grade: A
 go canon November 12, 2008

had both this and the canon. you get what you pay for. and you get better pictures with the canon wide glass on your camera. less distortion. and more vivid color. I returned the sigma.
Fantastic wide angle lens September 23, 2008

This is the lens that spends about 90 percent of the time on my 20D (I have six lenses!). In fact, I forgot I even owned the Sigma 10-20 until I looked. The lens has very good build quality and the zoom touch is superb. I never really even look at the lens or realize that it's there!
Images are very good, always good colors, tones and good sharpness and saturation. The wide angle offers a little distortion but that is to be expected on 10mm!
The zoom range is somewhat limited but you get used to it. Most of my shots are at either 10mm or 20mm. Zooming is so easy I can't recall even using the zoom, however when I look at my photos they have been taken at different focal lengths.
To me, the purpose of a great camera and a great lens is that they work so well they "get out of the way" of the creative process. This zoom truly "gets out of the way", your so close to the action that you can take small group shots standing about six feet from your subjects. This lens really excels at close in people shots, specially in tight situations.
You can also interact with your subjects, because your not standing 20 feet back asking people to look at the canary standing on your shoulder. You can have a normal conversation at a normal distance from your subjects then raise your camera and get a half upper body shot - not too shabby.
If you take photos of people or working at events where you need lots of shots of people, individually or in small groups, this lens excels. Dare I say it could be an excellent "walk around" lens?
