• Streamlined workflows using 10-bit D-Log M color profile with standard microSD media handling

When not to compare directly

Do not compare the DJI Osmo Action 6 and DJI Osmo Action 4 directly when project requirements specifically mandate high-resolution 8K workflows, native variable-aperture optics, or onboard emergency storage, as the DJI Osmo Action 4 is strictly a fixed-aperture (f/2.8), 4K-max, external-card-only device.

What are the key differences between Action 6 and Action 4?

• Sensor & Optics

  The DJI Osmo Action 6 provides a larger 1/1.1-inch 38 MP sensor with a variable f/2.0-f/4.0 aperture, whereas the DJI Osmo Action 4 uses a smaller 1/1.3-inch sensor with a fixed f/2.8 lens.

  Action 6: DJI Osmo Action 6 features a larger 1/1.1-inch sensor with 38 MP resolution and a variable aperture ranging from f/2.0 to f/4.0, providing superior low-light intake at f/2.0 and enhanced depth-of-field control.

  Action 4: DJI Osmo Action 4 utilizes a smaller 1/1.3-inch image sensor paired with a fixed f/2.8 aperture lens, offering fixed light transmission and standard depth of field.

  Scores — Action 6: 9.2/10, Action 4: 7.4/10

  Determines low-light sensitivity, dynamic range, sharpness, and depth-of-field control during high-speed action recording.
