Nikon only told us that it will be a “newly developed high-resolution stacked FX sensor”. The rumor was that three different sensors were tested: 45-46MP, 50MP, and 60MP. The latest info I received is that the Z9 will have a 45MP sensor that will allow up to 30 fps (previous rumors indicated “only” 20 fps). Here is an updated recap of the Nikon Z9 rumored specifications so far:
Newly developed 45MP high-resolution stacked FX sensor
30 fps
Integrated vertical grip handle
The Z9 is described as a D6 body combined with EOS R5 imaging, α9II AF, and blackout-free EVF
Nikon confirmed that the Z9 will be better than the D6
Multishot-mode
16-bit RAW option
8k30p, 4k120/60/30p (support for 8K video recording)
