Product Description
Sigma provides the new ultra-wide angle zoom lens from 15mm and this lens is the first of its kind in the world. It can be useful for images of landscapes, large buildings, group photographs or even more. The perspective that changes with the angle-of-view gives picture an extraordinary feeling. Delicate compositions can be adjusted by lens zooming and this is helpful for close-up photography. Provides deep depth of field with its short focal length for amazing photographic expressions. This ultra-wide zoom lens covers a large wide-angle range from 15 mm to 30 mm. With a minimum focusing distance of 30 cm(11.8 inches) throughout the entire zoom range, it is an ideal lens for Digital SLR Cameras. It incorporates hybrid aspherical lens in the front lens group to minimize distortion and astigmatism, and molded glass aspherical lens in the rear lens group to minimize spherical aberration. Minimization of the distortion is a most important issue for zoom lens, but Sigma has succeeded, to provide image quality with minimal distortion by employing aspherical lenses. This lens in corporates an internal focusing system, which eliminates front lens rotation. Since focusing do not change its overall length, this lens is easy to hold and use. Also it is allowing the use of a Petal-type Hood. The lens also incorporates Dual-Focus (DF) mechanism. It is easy to hold the lens, since the focusing ring does not rotate during auto-focus, yet it provides adequate focusing torque of the focusing ring during manual focusing of the lens.

 Read dpreview before you buy July 28, 2010

Mechanically well constructed. Come with pinch-type lens cap and hood, as well as boxy carrying case you can thread onto a belt or rigging.
I wasn't going to spend extra money for the Canon glass since I anticipate using this lens only occasionally. I figured I'd go with the Sigma over the Tamron because the Tamron is a 77 mm filter while the Sigma shares a 72 mm filter with my main everyday lens. I fully read the review on dpreview about the lens' performance at various apertures, but I wasn't prepared for how soft the picture looked at 10mm F4! Don't rush to return your lens if you're surprised by the poor quality of the test shot, try F11 or F13 where the lens performs the best. This does mean that I'll have to be more thoughtful capturing a landscape than just setting the aperture to F22 and firing away. No quality problems in my copy when stopped down, unlike other mentions here.

This lens is amazing, strong, durable, and makes some awesome picture. I am an amateur photographer and bought this lens for a trip to Wyoming. I have a Nikon D60 but it is a beast and this lens makes my pictures look professional. I have taken some amazing pics of Yellowstone, Devils Tower, and the mountains of Wyoming. The quality of the picture sometimes lacks, but nothing that can't be fixed by photoshop or lightroom and for less than 500 bucks it is one cheapest and best wide angles you can get. You can also take some very interesting close up pics (for example I take close ups pics of my pets) with this lens but you have to have an external flash.
I say this lens is durable because it has been dropped twice. Once on the concrete path at Devils Tower, it got knocked out of my coat pocket while changing lens and the second time got knocked of the car seat and then stepped on by somebody that wasn't paying attention and the filter got smashed into a million pieces. So to say the least it has been through a lot. but it still works perfectly which is a miracle in itself.
If you are like me and don't have much money and want a wide angle lens this is a the way to go and you will not be disappointed. I recommend you buy it a filter for protection (Zeikos sells a 77mm for 8 bucks and it is what saved my lens) and it comes with it's own case so keep it in it's case when not in use.
Bought this lens used from Amazon Warehouse Deals July 9, 2010

After spending countless hours reviewing the various UWA lenses, I settled on this Sigma 10-20mm lens. It isn't the fastest wide angle out there, but it is the only one at 10mm focal length at it's widest setting. After all, If you are going to buy a wide angle lens, why not buy the widest available (yet still affordable). I paid extra for next day shipping and the lens arrived promptly at 2:00 pm the next day. Although this is an Amazon purchase, I found the copy I bought from Amazon Warehouse deals, sold as a USED lens. The price was $80 less than brand new so I figured I'd give it a try, knowing that I could always return it if it was not in good shape.
When the package arrived, I expected to open the box and see a used lens wrapped in paper or bubble wrap. I was surprised to find that the lens came in the original box with original warranty card still in place. But best of all, this lens appeared to be new in every way. There were a few fingerprints on the front element which I took care of with a lens tissue, but other than that, there was not so much as a hint of wear or handling issues.
But the real test is how this lens works (or not works). I put it on my D90 and it instantly recognized the lens and was ready to go.
So far, I have taken about a hundred test images to be sure I got a good copy of this lens. I was particularly impressed when i took a picture of the front of my wife's Ford Escape at 10mm and about 6 feet away. After bringing the image into my PC, The photo was tack sharp but the real surprise was that I could read the serial number on the small decals of her license plate as if I had used my sharpest Nikon fixed focal length lens.
I am so pleased that Amazon's warehouse Deals had this (used?) lens for sale the day I decided to purchase one. If I didn't know better, and if there had not been finger prints on the front element when I opened the box, I would have sworn that this lens was brand new.
Great job Amazon.

 Crap! Go with Canon or Tokina July 4, 2010

I bought this lens never was happy with the results. Not very sharp and to much distortion. Very nice wide angle, but I did not feel the optics were very good. Recently purchased the Tokina 12-24 and could not be more happy! Only thing better would either be the Canon 10-22 or the Tokina 11-16. Save you money and buy one of these. I use my wide angle more then my kit, and it is worth investing in.
Great bang for the buck!!! June 27, 2010

Bought this lense a couple of weeks ago and works like a charm. Great crisp and fast autofocus. The only small problem that I have with it, is that the f stop only goes to 4. Doesnt work that well in low light without a tripode. I have used the Canon equivalent and in comparisson this stacks up pretty well.
