Nikon has released an updated firmware for its D810 D-SLR. The new version, C 1.10, fixes several issues. It also adds the additional functionality of controlling external recorders that support the Atomos Open Protocol, connected through HDMI port.
The details of fixes are 
as follows:
- Incorrect distances were shown in the camera playback info display for photographs taken with an optional flash unit in distance-priority manual (GN) mode.
- The brightness of the live view photography display would not change when a command dial was rotated to adjust exposure compensation with On (Auto reset) selected for b Metering/exposure > b4 Easy exposure compensation > Easy exposure compensation in the CUSTOM SETTING MENU.
- Although the preview button would stop the lens down to maximum aperture when assigned the Preview role, the maximum aperture indicator would not appear in the monitor.
- In rare cases, the shutter would not be released when the user attempted to take photographs in movie live view.
- About 4 seconds of static could be heard on audio recorded with external HDMI recorders during movie live view.
- The shutter speed, aperture, and ISO sensitivity displayed in the monitor during movie live view would differ from values in the final movie file.
- Volume could sometimes not be adjusted if movies were played with indicators hidden during full-frame playback (None (image only)).
- Exposure compensation would fail to produce the desired results if a negative value was selected when NEF (RAW) images were processed using the NEF (RAW) processing option in the RETOUCH MENU.
- Images would in rare cases fail to record correctly with HDR (high dynamic range) selected in the SHOOTING MENU.
- If On was selected for Exposure smoothing during interval timer photography, every frame after the first would be overexposed.
- File numbers were not assigned in the proper sequence.
- In some languages, characters or parts of characters would be missing from the SETUP MENU > Location data > Position display.
- In some languages, characters or parts of characters would be missing from the SETUP MENU > AF fine-tune > List saved values display.
- Some help text has been changed.
