p.2 #1 · FTZ II & aperture rings - what the heck Nikon!
UPDATE !! FTZ brings a benefit over aperture rings!
Playing with my Zeiss .zf2 lens on the Z5 II with FTZ I noticed something. As I stop down the aperture with the finger wheel on the body, the physical aperture in the lens closes until you hit f/5.6 then it stops closing. If you want to shoot at f/8 or f/11, system will keep the lens at f/5.6 while you focus, stopping down to your chosen aperture when the shot is taken.
With my native Z Voigtlander lenses, I have to manually set the aperture to where I want it for focus purposes, then switch it to where I want for image capture purposes. So, shooting at f/8, I open the aperture to maybe f/2.8 for focus, the turn the ring to f/8 to take the image.
The FTZ partially automates that process. I just wish there was a configuration setting to pick the min aperture for focusing. I think I'd rather have it stop at f/2.8 or maybe f/4.

All chipped lenses (including first and third party Z glass) operate in this way on Z. The most narrow aperture they will stay at during focusing is f5.6, meaning any shots beyond that aren't actually WYSIWIG in the viewfinder in regards to depth of field.
Several of the newest Z bodies allow the lens to stay fully wide open during this instead for better AF performance.
You most definitely should NOT be focusing a MF lens at a very different aperture than you are shooting at, as some of these lenses will shift focus as they get stopped down.
