have you tried a long lens on the z6 w/ FTZ and experienced the AF issue of focus long then short ? I'm curious if that's fixedI've applied the update to my Z6 and both my wifes & my Z50, and all three of our FTZ's.
Installs were the same as every other Nikon firmware update I've done. Quick, clean, no issues.
I had just a few minutes to sit in the backyard during lunch. Both bodies seem to perform about the same as pre-update, based on only a very brief time to shoot. The Z50 is still a tad quicker to aquire focus than the Z6 - no change there. I did not try Auto-Area AF or tracking, which is where some of the updates were referenced so I probably didn't test anything relevant to the update(s).
