Sigma will always be guaranteed a place in the history books as pioneers of the
Their advanced super wide angle technology was developed far earlier than any of
Sigma designed and produced the first wide-angle zoom lens, the zoom gamma 21-35mm F3.5-4.2, in 1979. The wide-angle zoom category didn’t even exist before this date.
The market comprised only
telephoto zoom lenses with most people believing that wide angle zooms were impossible to develop. However Sigma’s advanced design and pioneering technology went on to prove them wrong and strongly influence subsequent product development.
Optimized for Digital SLR Cameras
Four Special Low Dispersion (SLD) glass elements are provided for effective compensation of color
aberration, which is a common problem with super-wide angle lenses. Two pieces of molded glass and three
aspherical lenses, including two molded glass aspherical lens elements, offer excellent correction for linear distortion as well as all types of aberration. It is an ideal lens for Digital SLR Cameras as well as film SLR cameras.

Fantastic glass, June 25, 2009
By RonAnnArbor (Ann Arbor, MI United States)
I got this for my Nikon D700 when looking for a wide-angle lens that wouldn't break the bank and had a large wide angle view.
Wow, was I surprised by the quality of this glass. It is the widest you can get for a full-format dSLR, and it is sharp across the entire focal range. I won't go into a detailed review here of the the glass -- you can google the reviews and the technical specs.
This is a fine wide angle lens for landscape shooting. It's a bit heavy and large, but the D700 is a great home for it!...One note: there is no way to put a standard filter on this lens, though there are workarounds. Still - with photoshop
you can go back and create the filter effects you might have wanted. For
purists, you will need to read about how to attach external filters if you need
to use one.
Wow. Great lens!, May 15, 2009

I'm lucky in that this lens has apparently jumped in price since I purchased to when I'm getting around to this review.
My first experience with Sigma was a 28-300 I had on a camera ages ago. The barrel oil canned and picture quality was so-so. I needed this lens for performing interior and exterior home remodeling pictures as part of a contract job.
First impressions when un-boxing. Wow. This is a different breed of lens than my first Sigma. The lens feels solid and well made. Has a nice carry case that comes with it, even though I don't use them.
My first day of playing with the lens was a cloudless day at a tree preservation high up on a hill. First couple of shots I noticed a lot of vignetting on the LCD. I realized then that the lens hood on the end of the lens slides off easily to expose, Popeye!
When not shooting with the hood, you have to be very wary of the sun angles, as you'll get immense flare from the intense curvature of the lens.
The lens takes some learning because of distortion and your physical relationships to your subject. Don't expect, as with any lens, to throw it on and start shooting keepers.
I've found far more uses for this lens that I originally anticipated. In addition to the interior photography, I've found it quite useful in providing a unique venue snapshot when shooting weddings. I will try to upload some customer photos from the lens.

Sigma Japan has announced a new wide angle zoom lens, the 12 - 24 mm F4.5-5.6 EX DG HSM. This lens is clearly aimed at providing a good wide angle range for digital SLR's as well as ultra wide angle for film SLR's. On the Sigma SD9 (1.7x crop) this lens would provide the same field of view as a 20-41 mm lens, on the Canon EOS-10D/300D this would be approx. 19-38 mm. This new lens will be available in Sigma, Canon, Nikon, Pentax (non-HSM) and Minolta (non-HSM) mounts and has an estimated Japanese list price of 99,000 YEN ($901 at todays exchange rate).
