That's a huge distortion Fons. Are those lens-profiles in Camera Raw working okay? I noticed some extreme differences just when applying that automatic lens-profile. It seemed to work the other way around. So I disabled it and made it manually in CC. Or there is something wrong with your lens?

Df 17-35/2.8 look at the huge distortion at the wide end, even after lensprofile correction in ps;and it got a work out at niks'.
