Thanks for the explanation about refocusing the corners. Wasn't sure about that.
So getting those gazillion complaints about how much people would shoot wide open with main subject in the corner does also say something about the importance of corners sharpness with this lens, doesn't it? Rate it the way you like, I'm aware of comparing Nikon and Sigma in the Canon board and grateful not to be thrown out.
And now, since I checked, I'm also aware of a price gap of 500 francs between Canon and Nikon version. And since you rated the Canon version already, the situation is different because Canon is not asking 100% more. 104% to be accurate and that goes with a bundled polarizer on the Sigma... yes, a Sigma polarizer, not a China copy.
