Product Description
10-20mm F4-5.6 EX DC lens allows enjoyment of super wide-angle photography and it is a very powerful tool for indoor shooting and landscape photography with APS-C size image sensors of digital SLR cameras.Wide angle of view (102.4 ? at 10mm and 63.8 ? at 20mm) offers the photographer greater freedom of expression. Three 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. It has a minimum focusing distance of 24cm (9.4") 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.
Amazon.com Product Description
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. - Lens construction: 14 elements in 10 groups

 Good gravy! What a lens!! March 17, 2010
Andrew
I think this has to be the best lens I've ever purchased. It's not as quiet as, say, the Canon 18-55mm kit lens or something comparable but it's a fine and INEXPENSIVE (a relative term in photography) replacement to Canon's model.
Very durable, clean, and I have no idea what people are saying about distortion. Vignetting has not been noticed. Amazing!!
Excellent lens! March 5, 2010

I love these lens! Great for landscape photography!Will recommend my friends to get this cos' it only costs half as much as the Nikon ones.
Sigma WIDE Angle Lens February 21, 2010
Brandon! (Sacramento, CA USA)
This is a good lens. Let's get that right out there in the open. It's a good lens.
The price is right on. For 500 bucks, it's tough to beat. It's a great budget lens, and being able to shoot 10mm is something I wouldn't be able to afford at the professional level. The lens includes a hood, the build is pretty tough, and it's Sigma, so it's probably gonna be reliable (my experience with Sigma has been really good so far).
I was originally shopping for a 10 or 15mm prime lens (prime meaning it doesn't have any zoom, it's just one lens "size"). I couldn't find one, but I'm glad I couldn't. While 10mm is a great wide angle, I'll admit it's nice to have the option to go a little tighter without swapping lenses. (I want a 10-500mm f/1.4 lens, someday...) Plus, I don't mind any loss of possible aperture: with a 10mm lens, I won't be doing many portraits. In fact, I bought the lens for landscapes and cityscapes, and if I was anything in focus, I'll be shooting much higher than f/4.
Speaking of shooting, it's an average lens in terms of focus and noise, perhaps a little below average on focus speed. The photos feel a little soft in terms of focus, but again, this is more of a budget lens than anything pro-pro-fessional. There's some distortion/pin cushioning at 10mm on the edges of the photos, however it's not terribly rampant and can be ignored if you're not on location for National Geographic.
The last time I photographed Lake Tahoe was with a 24mm zoom lens, so my experiences here were very different this time around. I enjoyed the lens and the results I got, and I think it's an improvement from either my 24 or 18mm lenses. For fun, I swapped in my 50 prime and took a photo, and the differences are huge. 50 suddenly felt like a telescope for viewing Saturn. But back at 10mm, I was photographing the whole lake, and I loved it.

This is really a fabulous Lens. You can read all about the technical stuff somewhere else.
A word of caution when ordering through amazon though. If you need it right away, make sure it's being shipped by Amazon, and not a third party.
I had ordered this, an paid for expedited shipping. It was still almost a week before it arrived.
If you need it the next day, get it from B&H
A breath of fresh air for DX DSLR owners. February 4, 2010

First words? "Wow."
Second words? "Why did I wait this long?"
From 2004-2008, I owned a Nikon D70. From 2008 on, I've owned a Nikon D90. Both DX bodies, both great. My widest lenses through all of those years was always an 18mm. That was usually "wide-enough" for me, but there were occasions where I couldn't *quite* frame the photo the way I wanted. Couldn't *quite* fit it all in the frame. As this lens has been out for a few years, I've toyed on and off with buying one. I finally recently did, and I'm blown away.
I should have bought this lens 4 years ago. This lens has opened my eyes to how restrictive 18mm on a DX-body can be. You don't understand "wide" until you've shot with a lens like this.
I'm generally a Nikkor guy. I love my Nikon bodies, and I generally like to use Nikkor glass. But I've got to say, this is my second Sigma lens, and both have greatly exceeded my expectations. The build-quality on this thing is great. Zero regrets. And for half the price as Nikkor's 10-24mm, it's a good deal. Optically and mechanically, it seems flawless. Sharp, contrasty, and not a lot of distortion for as wide as this is.
And yes, there's a newer version of this lens, a fixed-aperture f3.5 10-20. For me it doesn't matter much as I'm mostly using this lens down around 10mm anyway, where the difference between f4 and f3.5 is nearly meaningless. And it's so wide even at 20mm, that shake issues (due to slow shutter necessitated by f5.6) are mostly a moot point. IMHO, fixed apertures matter a whole lot more for telephoto lenses than they do for wides, and this lens is super-wide.
From a creative standpoint, this lens is astounding. It's not just about being wide; capturing the whole skyline, the whole meadow, or the whole mountain range. It's really about perspective and depth. Even a photo of something as mundane as a soda can on a coffee table takes on a whole new perspective (literally!) when shot with a super-wide like this. Get close. Really close. Closer. Pow! Your photography will never be the same. Just as a telephoto lens compresses distance (distant objects seem closer), wide angle really expands distance. Compose a flower or some other small object up close, with an expansive background landscape, at 10mm, and the resulting photo will nearly leap out at you. Push it further, closer to the foreground object, and the flower will be enormous while the distant mountain peaks are minuscule. Amazing creative potential.
This lens is about as wide as you can go on a DX body. It's probably not an 'every-day' or 'walkaround' lens for most people. Myself included. But I can say that if I could only grab *two* lenses for a day of casual and fun shooting, there's a pretty good chance I'd grab this 10-20 right after either my 35mm or 50mm prime.
