Manufacturer's Description
10-20mm F4-5.6 EX DC HSM 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, and the models which are equipped with HSM system provide quiet, high speed autofocus shooting and also offer full time manual focusing. 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.

Razor sharp performance
Third party lens manufacturers are usually best given a wide berth if you want really good glass. This offering from Sigma is awesome. I use this lens professionally and regularly produce twenty inch wide prints. Chromatic abberation is minimal far less than expected from a lens offering this angle of view (15mm equivalent on 35mm). Barrel distortion is there at 10mm but this is no drawback after all the results from this optic are meant to be dramatic. I simply cannot fault the resolution from its use on my D200. Save money go for the Sigma over the Nikon equivalent you wont be dissapointed.

A cracker for the money!
Get a good one and this lens will give anybody great results. Bit of vignetting wide open and it has occasional flare issues (comes with a hood, so use it!), but other than that it has massively impressed me. Tested it alongside a Canon 10-22mm and the Sigma beat it for sharpness at almost every point. I use a Hama 77mm circular polariser on the front.

Great value lens!

**UPDATE** Been using this for well over a year now with no problems whatsoever. It remains almost permanently attached to my 400D and I've taken thousands of pics with it. It's a joy to use: sturdy, smooth and fast focusing. The matt finish that Sigma use on their lenses is my only gripe. I've thought about upgrading, but came to the conclusion that I'd need to go to a 5D with a 17-40 or 16-35 to see a noticeable difference in quality, and that's one expensive upgrade! My favourite bit of gear.

**FINAL UPDATE** I was right. I ended up buying a 1Ds (in preference to a 5D or 5DII) and 17-40 and I am now seeing better results than my 40D and 10-20 combo. An expensive upgrade for results that certainly aren't night and day better. The 10-20 has found a new home and the chap I sold it to loves it as much as I did. A brilliant lens and fantastic entry into the world of UWA.

I love this lens!
Anyone looking at this will know the technical stuff so i'm not going to bother with that!

I bought this for a trip to San Fracisco, Yosemite & the Grand Canyon. I am so glad I did. It is a fantastic lens, quick, responsive, quiet and above all the photos are sharp!

At it's widest setting there is a a good deal of vignetting if the lighting isn't spot on, but once you get used to it, it's fairly easy to overcome. I am using it on a Canon 350d and have been really impressed with the results.

I have had a canvas made from a photo of the Golden Gate bridge at sunrise and a photo at sunset taken at Rossnowlagh beach in Donegal, Ireland.

I would recommend purchasing the Sigma EX 77mm circular polarising filter as it works wonders on this lens.

The picture in the gallery was taken mid afternoon (not always the best for photos) at 10mm, F/9, 1/200sec.
