How does the Dual Native ISO Fusion work on DJI Mavic 4 Pro?

The DJI Mavic 4 Pro uses Dual Native ISO Fusion in most shooting modes. It blends the signals from two analogue gain circuits (low gain and high gain) to deliver more dynamic range, especially in high-contrast scenes.

Modes that don't use Dual Native ISO Fusion

  • High-resolution photos: 100MP on the 28mm main camera, 48MP on the 70mm medium tele camera and 50MP on the 168mm tele camera.

  • Slow Motion video: on all three cameras.

  • 2.7K vertical video at 48–60fps: on the 70mm medium tele and 168mm tele cameras.

How ISO works in these modes

Instead of blending the two circuits, the camera switches between them at a fixed native ISO value:

  • Photos: the native ISO values are 100 (low gain) and 400 (high gain). Below ISO 400 the camera uses the low-gain circuit; at ISO 400 and above it uses the high-gain circuit.

  • Video in Normal, D-Log M or HLG: the native ISO values are 100 and 400.

  • Video in D-Log: the native ISO values are 400 and 1600.

In video, ISO settings below the higher value use the low-gain circuit. Once you pass that value, the high-gain circuit takes over. This keeps image quality optimal for your ISO setting and colour profile.
