Nikon has issued a firmware update for the Nikon Z7. Firmware version 1.02 is now available and brings a couple of fixes for Nikon's flagship full-frame mirrorless camera, including a flickering issue, an ISO selection problem, and an occasional crash that could occur when displaying certain Raw files.

Below is the full changelog of changes made in firmware version 1.02 for the Nikon Z7:

  • Fixed an issue that caused the display to flicker if pictures were scrolled during playback zoom after the user had taken pictures using the viewfinder with Prioritize viewfinder selected for monitor mode and then removed his or her eye from the viewfinder before starting playback.
  • Fixed an issue that caused Capture NX-D or ViewNX-i to crash when displaying NEF (RAW) pictures taken with the following options selected for HDR (high dynamic range) in the PHOTO SHOOTING MENU:
    • HDR mode: On (series) or On (single photo)
    • Save individual images (NEF): On
  • Fixed an issue that allowed the camera to exceed the value chosen for ISO sensitivity settings > Maximum sensitivity in the MOVIE SHOOTING MENU if it was from ISO 200 to 20,000 and On was selected for MOVIE SHOOTING MENU > Electronic VR.
  • Updated some help displays.
