I can now confirm that Nikon is indeed working on a new Nikon FTZ2 adapter – I received multiple tips from reliable sources. The new adapter will have a re-designed body (probably without the bump at the bott0m) and this should avoid problems when mounting Z cameras on a tripod or when using underwater housings. I am not sure if the new adapter will be announced together with the Z9 camera. Stay tuned for more details.
