Nikon has released new firmware updates for both the Z6 and Z7 full-frame mirrorless cameras. Both firmware are marked as version 2.10 “C”, and are fundamentally identical in features and fixes. They add support for the two new Z mount lenses, change the way a couple of things work and fix a lot of bugs.

What they don’t do is add CFexpress support or RAW output over HDMI, the latter of which is something that Z6 Filmmaker’s Kit owners have already been waiting for for quite a long time.

Firmware version 2.10 C (for both the Z6 and Z7) adds support for optical VR with Nikon’s NIKKOR Z DX 16–50mm F3.5–6.3 VR and NIKKOR Z DX 50–250mm F4.5–6.3 VR Z-mount lenses. It also enables lens control rings to adjust ISO sensitivity, a setting that can be found under the ‘Custom Setting Menu.’

Beyond that, the firmware addresses the following issues for both the Z6 and Z7:

• Added supported for optical VR with NIKKOR Z DX 16–50mm f/3.5–6.3 VR and NIKKOR Z DX 50–250mm f/4.5–6.3 VR Z-mount lenses. Note that attaching these lenses disables the Mechanical shutter option for Custom Setting d5 (Shutter type) in Group d (Shooting/display) of the CUSTOM SETTING MENU, leaving a choice of Auto and Electronic front-curtain shutter options only.
• ISO sensitivity can now be adjusted using the lens control ring, and ISO sensitivity has been added to the options available for Custom Setting f2 (Custom control assignment) > Lens control ring in Group f (Controls) of the CUSTOM SETTING MENU.
• As of November 14, 2019, the aperture display in the lens info panel for NIKKOR Z 24–70mm f/2.8 S and NIKKOR Z 58mm f/0.95 S Noct lenses shows both the current aperture and adjacent aperture values in modes A and M.
• When On was selected for Auto ISO sensitivity control and an option that does not include “slow sync” was selected for Flash mode, shutter speed was formerly restricted to values between those chosen for Custom Settings e1 (Flash sync speed) and e2 (Flash shutter speed), but this has now been changed to match the behavior of digital SLR cameras, with the result that the minimum shutter speed now corresponds to the value selected for Auto ISO sensitivity control > Minimum shutter speed.
• Fixed an issue that in extremely rare cases resulted in the camera failing to correctly record movies with 1920×1080; 120p selected for Frame size/frame rate.
• Fixed an issue that occasionally resulted in “noise” in the form of white lines at the bottom of the display when the electronic viewfinder was on.
• Fixed an issue that in rare cases resulted in “noise” in the form of fine horizontal lines appearing throughout the frame in movies and the live view display.
• Fixed errors in the UTC time zones for the following three cities in the Time zone and date > Time zone display in the SETUP MENU:
  • Caracas: was -4:30, is now -4:00
  • Casablanca: was 00:00, is now +1:00
  • Ankara: was +2:00, is now +3:00
• Fixed an issue that resulted in an incorrect date of creation being displayed in the Windows 10 “properties” dialogs for movies and time-lapse movies created with the camera, as well as copies created with camera movie editing controls.
