And yes, I've seen this distortion before, commonly on ultrawide angle lenses on 35mm.
Yes, the f-stops was different. Usually around f/8 when focused far and f/16 or f/22 when close.

Swirled and mushy corners is what I usually get from few of my Nikkors, 35/1.4 AIS, for an example, has the mushiest corners even stopped down to f/4.
