“The Sigma 10-20mm F/4-5.6 super wide angle lens turned in a good performance, but has some problems. Flare/veiling glare is bad wide open at all focal lengths, and focusing problems keep you checking your shots, instead of enjoying your day… This lens is very good if you shoot at F/8-11; you won’t need to worry about focusing issues, because you’ll have a huge DOF, and flare is mostly gone at F/8 as I stated earlier.”
rating: N/A reviews the Sigma 10-20mm f/4-5.6 EX DC HSM and writes;
“The Imatest lab tests show very good resolution, second to Nikon at widest angle, but it is the most prone to fringing, by quite a high degree. At 20mm this is better controlled, while distortion is very well controlled throughout the range. “

“Sigma 10-20mm f/4-5.6 EX DC HSM is a great value for your money. The lens is one of the widest zoom lenses for APS-C dSLRs available on the market. Its build quality matches (and some might even claim exceeds) that of a Canon’s L lens. Image quality rivals other ultra wide zooms on the market. “
Rating: ★★★★☆ reviews the Sigma 10-20mm f/4-5.6 EX DC HSM and writes;
“..the Sigma 10-20mm has a pleasant heft to it, with a very solid feel in the hand. The focus and zoom controls operate smoothly… The bottom line seems to be that the Sigma 10-20mm f/4-5.6 EX DC HSM is a real bargain for an ultrawide zoom for sub-frame cameras. If you want to shoot really wide with your DSLR, this lens looks like a good way to go about it.”
Rating: ★★★★☆ reviews the Sigma 10-20mm f/4-5.6 EX DC HSM and writes;
“The Sigma 10-20mm lens has two major strong points: sharpness edge to edge and chromatic aberration. We found that sharpness at 12mm was very good in the center and did not diminish much at all in the image edges, even when shot wide-open. “
rating: N/A reviews the Sigma 10-20mm f/4-5.6 EX DC HSM and writes;
“This lens is sharp! At 20mm, resolution tests showed it matched, and at one point even slightly out performed the venerable Canon 17-40mm L. At 15mm it’s a little soft at the edges, although still nice in the centre, but by the time it gets down to the 10mm mark the edges have improved again. “
Rating: ★★★★☆ reviews the Sigma 10-20mm f/4-5.6 EX DC HSM and writes;
“The Sigma AF 10-20mm f/4-5.6 EX HSM DC showed a very good performance during the tests especially in terms of resolution. There’s some softness towards the extremes at 10mm @ f/4 but otherwise there’s really nothing to complain here “

Great lens for the price | Rating: ★★★★★
“I use this lens for taking photos for a newspaper. It is plenty sharp for my needs and allows for interesting shots. It fits all three of my Nikon cameras. Would recommend it to anyone wanting a new perspective in their photographs! “ – by R. Turner “Summerfield Press”

Very pleased | Rating: ★★★★☆
“This is an eceptional lens considering the price. If you are a perfectionist and want to do all sorts of lens test, this is not for you. But, if you are into photography and wand exceptional images this lens will work just fine and produce incredible images at a budget price. You can spend more that twice as much and get Nikon’s latest offering or spend more and get Sigma’s latest offering, but this lens will produce wonderful images!!! “ – by P. Caluori “Pete”

Outstanding lens | Rating: ★★★★★
“My first Sigma lens. Usually use Canon L lenses. I have had this for almost a year.The Sigma 10-20 is tack sharp. Something in the lens coating and/or glass really enhances sky/cloud contrast and color, making it look like a polarizing filter was used. The overall lens quality is excellent and I have no complaints. “ – by NoZama

I could not find the Canon lense….. but WOW! | Rating: ★★★★☆
“I was looking for the Canon lense that a professional photographer recommended. I stumbled on the Sigma lense and love it. The price was right, and the colors are amazing. I don’t think you can go wrong with this lense. I have been a sigma user before as I was building my camera bag and I just wanted a wide lense to get cool landscape pictures. This was the one.” – by Franco Sicilia Jr.

Great wide angle lens for Nikon DX Format | Rating: ★★★★★
“This is a great lens for Nikon DX format (digital). I didn’t expect the sharpness of my nikon 20 mm, or even my nikon 18-35 (both FX full frame), in that case I better go the nikon way (expensive). The most important is that I get back the wide angle I used to have in my FX cameras. I use it with a D70 and pictures look good. Be careful with on camera flashes, mine works only in the 17-20 mm range, you better put an extra flash in order to avoid shadows from the lens itself.” – by Alfonso Betancourt

A breath of fresh air for DX DSLR owners | Rating: ★★★★★
“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. “ – by Peter Chenoweth

Sigma WIDE Angle Lens | Rating: ★★★★★
“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)…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 “ – by Brandon!

This is a Great addition to any lens collection! | Rating: ★★★★☆
“Wow, what a difference between an 18 mm view and a 10 mm. I can see why they say that this lens if perfect for realtors. Indoors, you get the whole room in nice clear focus. Outdoors, oh my gosh! Especially with a CL polarizer.
My first real use was in Maui. Seascapes, landscapes and sunsets, fantastic. I don’t know if you can take a bad picture there though.”
– by David Juengel

Fantastic… | Rating: ★★★★★
“I researched ultra wide angle lenses for about two weeks before I finally bit the bullet and bought this lens. I really wanted to buy the Nikon 12-24mm, but for under a third of the cost, I decided on the Sigma. I was really surprised with how well this lens performs and how solid the lens is. Now that I’ve actually had the opportunity to try it out, it seems like a no-brainer.” – by Robert Wheland

Features & Specifications

Sigma 10-20mm f/4-5.6 EX DC HSM Specifications

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.
