No link at the bottom of the page.

Erwin (for whatever it is worth to the reader), said:

"...distortion is not visible"

That is wrt the Summicron-M (IV) introduced 1979 (the pre-ASPH)

And for your current lens, said:

"Distortion is negligible."

The Summicron (I) introduced 1958


f/2.0 "...distortion is only visible at the far out zones."

f/1.4 "...distortion is visible."

Sounds like for your low distortion needs the (IV) version would be better.
