I have the same camera. It's been a weird relationship. I was coming from a Nikon D750 and there's something about the images from the DSLR I prefer, in some ways. In other ways, I prefer the Z6II. The mirrorless images seem to feel more computationally made, like there's something of an oversharpening happening that I can't turn off or compensate for, and it seems to want to lift out my shadows, even in manual. So much of my work is meant to be dark.
Obviously, for video, it's amazing. Congratulations on the new hardware!
Thats an interesting point. I havent noticed it myself, the oversharpening, at least not yet. Maybe the viewfinder gives the impression/feeling that all you see is an all electronic image. You can always de sharpen in post-processing a bit.
