Continuing some shaprness testing at short distance in the telephoto range 70mm to 200 mm.
The lenses involved: 24-120 F4, 70-200 F4, 70-300 F3.5-F5.6, 85 F1.8G, Samyang 135 F2.
I'll go over the conclusions with some comparative shots.
The 70-300 that I have has a pretty bad decentering so corners are not going to be that reliable but at 70 and 85 in the center is better or as good as any from above zooms.
70 mm
24-120 vs 70-200
The 24-120 has both center and corners a touch worse at all apertures
