- Check your camera’s firmware version (Menu > Firmware version).
- Cross-reference with Nikon’s service manual for your model. The manual will list the minimum required Version (e.g., "Requires NIA Ver 5.21 or higher").
- Look at the lens compatibility – Modern Z-mount lenses often require Ver 5.40+ for AF calibration.
- If buying used gear from a tech, ask them which version they used. A mismatch is a red flag.
The software provides a graphical interface for tasks that are otherwise inaccessible through standard camera menus: Autofocus (AF) Calibration
- Look for
