Nikon today dropped the first firmware update for the Z9. The primary changes for version 1.10 are:
- Increased buffer at 20 fps for images taken with both NEF (High Efficiency*)+JPEG and JPEG+JPEG photography.
- Made Filtered playback criteria options into multi-selector toggles instead of requiring check marks.
An issue involving SB-5000 flash not firing was also fixed.
Note that the Filtered playback criteria change is part of my firmware wish list (#11), but there still are plenty of other menu options that need the same change.
