I've gotta say, after using the F-mount 35/1.8, 58/1.4, and 85/1.8, I really don't know that I'd sell any of those lenses for the Z-mount versions. Yes, the Z-mount lenses have quieter AF and are a bit sharper wide open, but you give up the manually-linked focusing ring and the way the lens renders specular highlights is interesting due to the optical design.
They're great lenses, but so too are the F-mount lenses which are plentiful and cheap, and work on my D500's to boot!
Wowza! Look at that 70-200/2.8S. I purchased the Z7 as a backup to the D850 for which I have the 24-70E and 70-200E. With the Z7 I also purchased the 24-70/4S kit lens so that I could use the Z7 + 24-70/4S as a simple, light, walk-around travel camera. The 24-70/2.8S and 70-200/2.8S do look really appealing. I can't wait to see sample portrait pics from the 70-200/2.8S. Expensive no doubt, but I really am anxious to see how it compares to D850 + 70-200/2.8E.
