For anyone that has purchased a Nikon Z9, especially recently (like me

) , Nikon has issued a "service advisory" (recall in other words) for units with certain serial numbers. The issue has to do with the lens release button and if your camera is potentially affected it needs to be returned for inspection/repair. I would expect that if you've registered the camera Nikon will get in touch.
The info and serial number checker is here :

Sadly mine is one of them and to say I'm a tad annoyed is something of an understatement.
