Sigma 12-24mm f/4.5-5.6 II DG HSM
(From Sigma lens literature) The Sigma Corporation is pleased to announce the new Sigma 12-24mm F4.5-5.6 II DG HSM. One SLD and four FLD glass elements compensate for color aberration and provide high image quality.Three glass mold elements and one hybrid aspherical lens give advanced performance and compact and lightweight construction. The Super Multi-Layer Coating reduces flare and ghosting. This lens has superior peripheral brightness and provides sharp and high contrast images even at the maximum apertures. Incorporation of HSM (Hyper Sonic Motor) ensures quiet and high speed auto focus, while allowing full-time manual focus override. This lens has a minimum focusing distance of 28cm (11.0") throughout the entire zoom range and a maximum magnification ratio of 1:6.4. In addition, this lens features splash proof design for use in harsh conditions.

Gostei da lente, uso-a com uma Nikon D700 e para fotos de paisagens com boa iluminação é excelente. Vejam algumas fotos no flickrhttp://www.flickr.com/photos/[email protected]/reviewed February 10th, 2014 (purchased for $870)
4 out of 10 points and not recommended by Yucel (15 reviews)12mm is very wideNot sharp enought in corners
I've tried this lens and the Tokina 11-16 and the Sigma 8-12mm DX lens on Nikon. On a D800 FX body, I prefer the 8-12mm Sigma image quality to the 12-24.reviewed January 23rd, 2013
That is, if I need image sharpness in corners, I think I get better output shooting the D800 in DX mode w a 8-16 than with an FX 12-24.

8 out of 10 points and recommended by nh_photofan (1 reviews)Excellent center sharpness. Good corner sharpness when stopped down. Good autofocus, fast and accurateSoft in corners at 12mm until f/11-16. Some CA seen.
Soft in corners at 12mm until f/11-f/16. A little more CA than I had hoped with all that FLD glass. More barrel distortion at 12mm (but easy to correct) than I saw in tests of original version lens (I don't have it). Not as good on full frame as the Sigma 8-16mm is on APS-C.reviewed August 31st, 2011 (purchased for $949)
Excellent landscape lens. Good corner sharpness when stopped down. Better than my beloved 17-40L Canon. (They have similar MTF charts). Good autofocus, fast and accurate.
I tested the new version vs Canon 17-24mm L at 17mm and 24mm focal lengths on Canon 5d (FF). The 12-24 has much better corner sharpness than the Canon at 17mm and equal or better corner sharpness at 24mm at all apertures. (Both are good at 24). At 12mm, the extreme corners (last 2-3mm) are very soft wide open and soft until f/11 (pixel peeping at 100%). No issues with sharpness when used on APS-H or Aps-C crop cameras. Not as sharp in corners as 14mm F2.8 Samyang/Rokinon.
10 out of 10 points and recommended by 3systemuser (19 reviews)sharp , almost never flare ,superfast AF,wide really wide, very well controlled distortion.a bit too much CA at long end, a bit more distortion than the old 12-24.
in japan , Canon version just out about 2 weeks a go and I bought it after testing it for a few days at a local big camera shop.reviewed August 13th, 2011 (purchased for $750)
I had Canon EF16-35f2.8L2 lens and Sigma 12-24original one and Zeiss 21f2.8ZE to compare to this lens, of course , the Zeiss 21 is the sharpest one of these but the new Sigma is not much worse than the Zeiss and a bit sharper than the Canon 16-35L2.
It AF very well , it is (I be lieve )selaed very well against moisture and light and compact , so it balances well on my 5D2.
I highly recommend this lens , I think all recent Sigma expensive lenses are quite good ,especially for their modest prices and the this one and the 85f1.4HSM are really outstanding for their relatively modest prices.
For 750US, you wont get any better.
One minor issue of this lens is its barrel distortion at 12mm is worse than the previous version that it replaces, though it is a still very well corrected lens.
PS. I heard that this lens may not come in Nikon mount because of the Nikon's crazy lawsuit against Sigma.
