Nikon has released the new version 2.4.0 firmware for the Nikon Z50, and it looks like the focus (no pun intended) for this one is eye-detection autofocus. Among other eye-detection AF performance improvements, the big one is eye-detection autofocus being added to the camera’s AF modes while recording video.
The last few updates for the Nikon Z50 have essentially been bug fixes or adding support for various new lenses. This one actually brings a new feature that should make the Nikon Z50 a much more attractive option for activities like vlogging. The notes for the new firmware all list improvements to the Eye-AF system.
Changes from “C” Firmware Version 2.30 to 2.40
• Eye-detection AF is now available during video recording.
• Improved eye-detection performance for [Auto-area AF].
• Improved the refresh rate for the focus points displayed in live view during subject-tracking and face/eye-detection AF.
As you can see from the above list, there aren’t too many changes, but they’re important ones for Nikon Z50 owners who want to shoot video or rely on the Eye-AF system at all. You can download the Nikon Z50 version 2.4.0 firmware update from the Nikon website.
