A little experiment (auto-distortion correction)
#1
I took a perfect (artificially created) distortion chart.

Then I distorted it to 7% and corrected it back (manually - not 100% accurate but good enough).

 

I've attached a crop 700% enlarged that illustrates the effect.

The "perfect image" does not show any grey values - just black & white, of course.

You may see that one pixel row got pretty dark (loss of edge contrast). Or in other words - loss of resolution.

 

It's, of course, no surprise but it clearly shows how lossy a correction of a rather "typical" MFT wide angle distortion really is there.
