8.5% native barrel distortion is... wild. Smile I wonder what kind of value is considered the borderline of the fisheye territory?

There is some tradeoff between distortion and MFT resolution values for wide angle lenses.

I wonder if it is OK to leave distortion less corrected when every other parameter is more or less optimized, and leave the end user to decide what distortion correction to apply during post-processing. Obviously, landscape people will want better edge sharness, architectural people will look for straight lines.
