I have posted an example here a while ago. I absolutely hated it. I tried a total of 4 of these lenses, two of which I took home. In the end I exchanged it for a Nikkor 14-24 with G-EOS adapter at twice the price. It's worth it. And the TS-E 17 is worth it even more, even at 3X the price.
At least, that's my opinion. I use the whole frame, compose for the whole frame, I don't crop, unless I really have no choice. The Sigma has incredible vignetting, has a lot of CA in th ecorners, and smears details in about 30 % of the picture area, making it totally useless for my purposes. If you look at the Juza review, you'll be able to spot this too, even though he seems to have a better specimen - just check the details in the granite rocks in the corners of the sample picture (snow landscape with stream). I'd really like to see how that looks in a 24"X 36" print, although I do think I know. I've seen this type of smearing in many more pics taken with the 12-24 EX on the internet. Also check the lateral CA in the top left and top right. My lenses had a bit more than this, though.
Indeed, its only advantages are that it can do 12 mm on FF, that it has virtually no distortion, and that it is (relatively) cheap.
Give me shifted images with the TS-E 17 any day, however, even if it is more of an effort, and three times the price.
Kind regards, Wim
