Summary: I think 15mm is the ideal ultra wide because with a FF outdoors it needed no lens correction in post processing, and indoors, at close quarters with a DX sensor the lens correction was minimal to set the horizontal and vertical lines straight.
Sigma 15-30mm f/3.5-4.5 EX DG Aspherical review by Perudog

Summary: If you have recently move to digital full frame ( Nikon d610 in my case), it won"t be long before you want to take advantage of the extra wide angle capability over cropped sensors. If like me you can't really justify the 14-24, this has prove to be a worthy substitute.
Pros: Terrific value for full frame when Nikon 14-24 is out of your budget...
Summary: Nice lens for the price.. Been looking to get a 17mm-50mm lens for my 5d mark ii.. These seem to be really good for landscape photography... They are some nice lens to have in your procession only if you are going to use them greatly..
Summary: The lens is a great performer for sharpness on my Nikon D600 but that's about it. For the range its unnecessarily large. It feels cheap too. The weight of my Nikon Nikkor 28mm (small) feels better than this. The AF/MF ring idea is neat, but useless. The flare is unbelievable.
Summary: I am so far, pleased with the lens, I recently got a Canon 5d, so I had to get rid of my Sigma 10-20 and replace it Wide angle lens that would work on a full frame. Since the Sigma 12-24 was out of my price range I settled with this one.
Conclusion: I am really quite impressed with this lens on my 5d. It is sharper than I expected with no decentering at all. Sharp to the edges with the exception of the extreme corners, but overall an excellent performer fo an UWA. It is large, but not too heavy. I find the focus plenty fast and accurate enough.
Pros: Sharp, accurate focus, nice color, well built.
Cons: Some vigeneting on full frame, but easily corrected. Need to watch for flare.
