Excellent ultra wide people still don't know about.
I've owned this lens since February and it is my favorite lens for hiking. Using an ultra wide angle lens is a unique experience that comes with a steeper learning curve then most other ranges. The biggest concept to grasp is scale, at 10mm an object 1 foot from your lens will look like its 5 feet away through the viewfinder, so composition and corner to corner attention to detail is crucial to getting a good image.Distortion at its widest is reasonable and expected.It is incredibly sharp in center to mid frame wide open, but it can get a little soft on the edges. I own the Canon 70-200mm 2.8 IS USM II , so I know what sharp looks like and I have no gripes with this sigma.Focus is quick and the rings have just the right amount of tension allowing for precise setting. Try laying on the ground and have a friend jump over you, ultra wide angle lens have incredibly large depths of field and it's hard for this lens to miss focus. Also the minimum...

Outsanding lens, well worth considering
This is the first short zoom that I've owned, so I can't compare it to any of its competition. I bought the f3.5 model to shoot in low-light because the built-in flash on my D60 casts a shadow with large caliber lenses. It's a quirky lens, for sure; but one well worth its price, overall. Is the Nikon version worth the extra $250? I'll never know. Those wanting a cheaper entry point would do well looking at the Tamron. Of all my lenses, I use this one most of all, with rave reviews. If I had to do it again, I'd have to go with the Sigma 8-16mm.Update:I have shot hundreds of photos with this lens over the ensuing months of ownership. My single complaint is vignetting, although it is only a problem with available-light indoor photography.While this lens shines when used outdoors for architectural photos, it also does a fantastic job indoors at weddings and parties, when you need to get the full table or dance shot but can't back up enough to frame it with a...

Product Description
Sigma Corporation is pleased to announce the new Sigma 10-20mm F3.5 EX DC HSM. This super-wide angle lens has a maximum aperture of F3.5 throughout the entire zoom range. With its wide angle view from 102.4 degrees it can produce striking images with exaggerated perspective. The maximum aperture of F3.5 is ideal for indoor shooting and it enables photographers to emphasize the subject. Two ELD (Extraordinary Low Dispersion) glass elements and a SLD (Special Low Dispersion) glass element provide excellent correction of color aberration. Four aspherical lenses provide correction for distortion and allow compact and lightweight construction. The Super Multi-Layer coating reduces flare and ghosting. High image quality is assured throughout the entire zoom range. The incorporation of HSM (Hyper-Sonic Motor) ensures a quiet and high-speed auto focus as well as full-time manual focusing capability. This lens has a minimum focusing distance of 9.4 inches (24cm) throughout the entire zoom range and a maximum magnification ratio of 1:6.6. The lens design incorporates an inner focusing system which eliminates front lens rotation, making the lens particularly suitable for using the Petal-type hood and polarizing filter. The Petal-type hood blocks extraneous light and reduces internal reflection. Top to learn more
Performs just as I expected.
I found this to be a very helpful lens added to my collection. It's great being able to take very wide angle shots without having to stand at a long distance away. The far edges of images can be somewhat soft and suffers from chromatic aberration, but I think any lens at this price level will also be the same; in most images, though, these imperfections do nothing to distract from the overall image, so I find it an acceptable trade-off for the new capabilities it opens up. I haven't yet had a chance to explore the full range of its qualities (like making panoramas and complete 360 domes), but I expect that these should work well with a program like Hugin. I have used Hugin's exposure fusion feature (like HDR+tone mapping in one step), though, and have been very pleased with the dramatic architectural photos which are possible.
