Product Description

Style: Canon SLR Camera


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
  • Angle of view: 102.4 to 63.8 degrees
  • Number of diaphragm blades: 6
  • Minimum aperture: f/22
  • Minimum focusing distance: 9.4 inches
  • Maximum magnification: 1:6.7
  • Filter size: 77mm

Style Name: Nikon SLR Camera
I went into a local camera store to look at the Nikon 12-24mm wide angle zoom to eventually augment the Nikon 50mm 1.8 and 18-200mm VR I currently use on my D200. After seeing the Sigma 10-20mm, taking test shots with it and the Nikon, and then printing the shots in the store, I walked out with the Sigma lens.

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.

Style Name: Pentax and Samsung SLR Camera Verified Purchase
I am rating this lens with only three stars because I am reviewing two lenses. Here is why:

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.

Style Name: Canon SLR Camera
there are currently 4 wide angle zoom choices available on the EF-S canon mount (d-rebel/xt/20d) canon 10-22, Sigma 12-24, sigma 10-20, tokina 12-24. Of these, sigma 12-24 is the only one which is usuable on a full frame sensor (canon 1d, 5d, possible future cameras). There is sizable difference in field of view between the 10 mm, and 12 mm. and the tokina is closer to 13 mm on its wide end. The sigma retails for about 2/3 the price of the canon. Optically they are very similar, with the canon having a larger maximum aperature, which is generally not important in a wide angle lens. The built construction is EX, they higher line of sigma, and it excellent. The focus motor is HSM, making it fast, and very accurate. Resolution chart show the sharpness to be very close to that of canon. The color and contrast is excellent, the flare and chromatic abberation genenrally well controlled. A fun lens to use, and excellent value.

Style Name: Nikon SLR Camera Verified Purchase
Before purchasing this lens, I looked at the Nikon 12-24 and the tokina 12-24. Both were more expensive, and claimed to be be excellent performers. After comparing all three, the Sigma 10-20 was the hands down winner in my book for a number of reasons.

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.
