Nope. No corrections. (distortion, CA or vignetting)
Yes, the Sigma is way wider, especially at infinity:

I think that explains the width, then. It's a lot closer to 35mm with distortion profiles applied. I haven't done careful tests yet, but I plan to find out how much resolution loss there is with it turned on. Doesn't seem too bad.
Lenses with distortion left in, even though it's often a good idea, are a nuisance for testers. On the one hand you might think that you should test with distortion correction applied, because that in a way is the design intent, and you certainly need to see how it performs then. But on the other hand, for many purposes photographers may prefer to have it turned off, so as to get maybe slightly better peripheral resolution and a bit of extra angle of view. So you end up tempted to test it both ways.
