Nikon has released firmware C 3.11 for the Z8, an update focused on three specific fixes for camera stability and workflow.
The version was released on September 16, 2026 and replaces C 3.10. In the change list from 3.10 to 3.11, Nikon does not add new shooting features, but fixes issues involving NX Tether, High-Frequency Flicker Reduction and Manage Picture Control.
The update is particularly relevant to photographers and filmmakers who use the Z8 for tethered shooting, assign custom controls for flicker handling or work with custom Picture Controls, because one of the bugs could cause the camera to stop responding during shooting in certain circumstances.
Three specific fixes in version 3.11
Nikon lists three fixes for the move from firmware C 3.10 to C 3.11:
- NX Tether: some unsupported functions could occasionally appear selectable while connected wirelessly to NX Tether.
- High-Frequency Flicker Reduction: the setting could sometimes change when the function and another function, such as Protect, were assigned to the same custom control.
- Picture Control: the camera could occasionally stop responding during shooting if certain operations were performed after changing settings in Manage Picture Control.
What it means for photographers and filmmakers
Firmware 3.11 is not a feature update like some of the Z8’s earlier major releases. It is mainly a reliability update. In professional use, however, the fixes touch three areas that can directly affect workflow: remote control, consistent behavior under flickering light and the use of custom Picture Controls.
Nikon also states that the update includes all changes from earlier firmware versions. If the camera is already running 3.11, there is no need to download the update again.
What to check before installing
Nikon gives specific warnings before the update. The firmware should not be updated with lenses other than NIKKOR Z lenses attached, or with mount adapters other than the FTZ II/FTZ, because failure to follow this precaution may cause the camera to malfunction.
A computer and card reader are required for installation. If the camera is being updated directly from firmware C 1.01 or earlier, IPTC presets stored in the camera will be deleted. Nikon advises copying them separately to a memory card first and loading them back after the update.
Download and installation
The firmware file is named Z_8_0311.bin and is approximately 94.46 MB. Nikon’s official page lists support for Z8 cameras running firmware C 1.00 through 3.10.
The installation follows Nikon’s standard process: copy the file to the root directory of a memory card formatted in the camera, insert the card into Slot 1 and select Firmware version from the Setup Menu. After installation, Nikon instructs users to check again that the camera is running C 3.11.
The firmware is available from the official Nikon Download Center.
Our take
This is not an update that changes what the Z8 can do, but a maintenance release targeting three real workflow issues. The fix for the camera becoming unresponsive after certain Picture Control operations is the most consequential, while the NX Tether and high-frequency flicker fixes are more specialized but still relevant in professional shooting environments.
