I am surprised that there has been no discussion on this.
Despite my comments in an earlier thread, I did buy a Z8 and find it an excellent, versatile camera.
I was away last week. On Thursday I took the Z8/24-70S out of my bag and found that the lens was disconnected. Having been offline for a few days, I logged into another website and learned of the recall. Checking on the Nikon UK website I found that my body was in the faulty batch, so I registered for the repair. Still waiting for a pickup date.
It is rather surprising that something so basic could go wrong (Nikon has been locking lenses to cameras for around 70 years), but at least they are dealing with this promptly (plus my Z8 will get an overall health check).
