As has been the case in the past, with everybody (apart seemingly from Canon) RED are flexing their claim to compressed RAW again.
The target this time is Nikon.
With the latest firmware update, the Z9 bravely has not one but two internal RAW codecs. N-RAW and now ProRes-RAW.
It might be unlikely Nikon will be able to continue to offer the internal RAW firmware update, so you can download it here for the time being, should you ever wish to own a Z9 in the future.
