The DJI Action series is probably GoPro's most serious threat; will the Action 4 threaten the Hero11?

Digital Camera World Verdict

The Osmo Action 4 isn't revolutionary in any respect except one – a significant one: the image sensor size leapfrogs the market leader. The camera also extends horizon balancing to useful resolutions and frame rates, and the waterproofing can go deeper. It adds up to mean, except a few scenarios, if you're happy with 4K, this is the best action camera of all.


  • +

    The best action camera in low light, bar none

  • +

    Waterproof to 18m (nearly double the GoPro Hero 11)

  • +

    Image stabilization and horizon balancing at up to 4K

  • +

    DJI's accessories include a long, light extension pole

  • +

    Noise cancelling three-mic system

  • +

    Excellent phone control app


  • -

    The horizon balance feature doesn't reach maximum frame rates

  • -

    No 5.3K video

  • -

    Magnetic clips catch fingers on removal

  • -

    Not a cheap option

DJI is most famous for its drones, but that is far from the only string to the company's bow. Undoubtedly the investment in producing a stable image from a rapidly vibrating and leaning gravity-defying box has helped the firm develop the tech for other lines including the DJI Pocket, camera gimbals, and the DJI Action series.

The latter is, as the name suggests, an Action camera. In its relatively short life (compared to market leader GoPro), DJI have made some serious attempts to innovate in the space, not least the quirky Osmo Action 2 which separated into a battery and camera unit. When used without the extended battery, this made the Action 2 much smaller than a GoPro.
