From Nikon:
Changes from “C” Firmware Version 1.00 to 1.01
Fixed the following issues:
- Users exiting Clean image sensor after adding it to and entering via MY MENU would be returned not to MY MENU but to the SETUP MENU.
- Photos taken with On selected for Long exposure NR would sometimes have increased noise or shadows with a greenish cast.
- Slight aperture reset lag would sometimes occur after shooting at shutter speeds under 1/10 s (type E and PC-E lenses excluded).
Downlad: Nikon D850 Firmware v.1.01
