>>3935667>>3935668In the first comparison the Sony is sharper and more detailed. You picked a spot in the test scene where this produces aliasing but aliasing is rare. Most people would prefer the sharper sensor over the softer one even if they occasionally get aliasing. It should be noted that X-Trans can also alias but tends to alias on different frequencies/patterns than Bayer. It's not free of aliasing despite the claims of Fuji fans.
As for the second example color NR is baked into Fuji RAW processing so high ISO areas of grey look far better on the Fuji ooc. To be fair you would have to compare them after applying some color NR to the Bayer sensor. The amount of NR required to eliminate color "splotching" from Bayer images at 25,600 is typically low enough that it's non-destructive though it might reduce saturation a bit. And if you look at Fuji in an area of color, you see that's exactly what's happening.
Given the age of the A7 sensor it's possible the XT4 is competitive at high ISO after you equalize for color NR. I don't know for sure and don't care to download/develop the RAWs right now.
All of that said: IMHO the XT4 is the superior camera to the A7 ***if*** you don't mind being locked into Fuji's ASP-C mount and lenses with no FF growth path.
