Interestingly, the Pana S1R is the sharpest of the 4. The Z7 seems to be the softest.
The noise level is quite high at ISO 3200 - worst on the A7R IV (unsurprisingly - it has 61mp).
Funnily the R5 has the worst moiree - despite the AA filter.
If you hover your mouse pointer over the [ i ] icon on the lower right corner (below each scene crop), you can get EXIF information that also tells which lens was used for the shot. When you see that Z7 uses 85/1.8G, and S1R uses Summicron 90/2, it becomes rather obvious how pointless comparing sharpness is.
Z7 also has base ISO of 64, not 100.
S1R has FSI sensor, so it will trade slightly better dynamic range at low ISO for slightly worse noise performance at high ISO . Also - not sure if it features dual-gain sensor architecture. We will have to wait to see how good DR is on R5, but I suspect it will be quite good.
You just can't have too many lenses...
