Nikon Z 9 Firmware Update Enhances AF, Subject Detection, & More

Nikon has released firmware version 5.30 for its full-frame/FX-format flagship mirrorless camera, the Nikon Z 9.

Firmware version 5.30 is available now for free download and adds improvements across the board to further enhance the capabilities of Nikon's top-of-the-line mirrorless camera. That said, it's following a fairly relaxed release schedule compared to many. V5.0 initially came out in March 2024, and the last update was V5.2 in April 2025.

Headline Additions

The new firmware adds multiple focus enhancements, starting with a significant improvement in subject acquisition, tracking and stability for fast-moving subjects such as athletes. Given the upcoming Winter Olympics and FIFA World Cup next year, this seems like good timing given the pro market the camera is aimed at.

Advanced subject detection now also works in other focus modes, making it easier to track the intended subject reliably in either single point or dynamic AF modes.

Usefully, subject detection can quickly be toggled on/off using a custom function button. The firmware also adds a new in-camera focus limiter, which allows the user to restrict the focus range to specific distances. 

Improvements have also been made to the Auto Capture function, with a new AF standby position, and other operability and performance updates such as face detection. Nikon reckons this means that the Z 9 now gives users the "ultimate and most intelligent" remote camera setup, without the need for any third-party triggering devices. 

Flexible Color Picture Control

Firmware version 5.30 adds support for Flexible Color Picture Control, which allows users to easily craft their own unique looks using NX Studio, Nikon's image browsing, processing, and editing desktop software. Parameters such as color hue, brightness, and contrast can all be adjusted using tools like Color Blender and Color Grading.

Settings configured in NX Studio can then be saved to a memory card and loaded onto the camera as Custom Picture Controls for shooting. These settings are reflected in the live view display, allowing users to preview results in real-time.

Additional Improvements 

• Focusing is now possible with the maximum aperture in live view.
• A magnification option of [400%] has been added to [Zoom on/off] available for Custom Settings.
• Use of an external microphone (wired/wireless) is now possible when recording voice memos.
• Extended the dimensions of focus areas available with [Wide-area AF (C1)] and [Wide-area AF (C2)] AF-area modes.
• Added [Flat Monochrome] and [Deep Tone Monochrome] Picture Controls.
• Added [USB streaming (UVC/UAC)] to [USB] in the [NETWORK MENU].
• Changed the specifications for uninterrupted video output to HDMI devices such as external monitors when recording ended.
• The headphone volume level can now be adjusted in the "i" menu during video recording.
