I will try again with the "Multiple Equations" enabled, thanks for the comment. Could this setting further reduce the vignetting?

Wolfgang,

Yes, the "multiple equations" mode allows CornerFix to deal with vignetting that has a more complex mathematical "shape". Normally not required, but it might help here. Although there's quite a lot of asymmetry in the mechanical vignetting that will be hard to correct, no matter how complex CornerFix's corrections become. The best solution will be to reduce the amount of mechanical vignetting....
