[QUOTE="Danno_RIP, post: 711801, member: 34269"] [USER=45839]@PhilM_TX[/USER] is the explanation from David Busch's "Nikon Z6 Digital Photography". It is from chapter 7, page 213. I think it gives a great explanation on how the VR works with adapted F mount lenses. "What happens to vibration reduction when you use an F-mount lens with the Z6 using the FTZ adapter?
