DJI’s Osmo Action 4 action camera features a new image sensor said to improve upon the one in the lower-priced Osmo Action 3.
The brand claims the new camera provides better image quality and easy usability in a reliable package.
The Action 4 sits above the Action 3 and the smaller, modular Action 2 in DJI's range, which launched in 2019 with the Osmo Action.
DJI says the Action 4 is an advanced-level action camera for enthusiasts and content creators who want the best image quality possible.
The camera features a new 1/1.3in sensor. This is larger than the GoPro Hero 11’s 1/1.7in sensor, and has a bigger equivalent pixel size.
Improved image quality
The 10-bit sensor can record 4k footage at up to 120fps according to DJI and is claimed to improve overall image quality.
RockSteady 3.0 technology and 360-degree HorizonSteady stabilisation are designed to keep the image stable and bounce-free. A 155-degree field of view provides a wider image spread than the 148 degrees found on the Hero 11 from GoPro.
If you like getting creative with your shots, the Action 4 also has DJI’s InvisiStick feature. This removes a selfie stick from the footage.
With many riders now experimenting with different ways of shooting compared to the usual chest or helmet cam POV (point of view), this could be a useful feature.
The DJI Osmo Action 4 is available now and is priced at £379/$399.
DJI's Multifunctional Battery Case is said to be a versatile power bank and charges up to three of the Osmo Action 4's batteries at once. This can also be used to charge other USB-powered devices.
It's available separately or as part of the Adventure Combo package, which includes the Osmo Action 4 and a range of accessories for £469/$499.
Familiar features
While there are claimed improvements in image quality over the Osmo Action 4's predecessor, many of the standout features from the Action 3 remain present.
As before, DJI claims the Action 4 will work in temperatures as low as -20°C and up to 45°C.
If bog snorkelling or water sports are more your thing, the Osmo Action 4 is claimed to be waterproof up to depths of 18 metres, almost double the GoPro Hero 11’s 10m rating.
The camera has a claimed runtime of up to 160 minutes (though DJI has not specified in which mode).
The fast-charging functionality means a battery can be recharged to 80 per cent in 18 minutes according to DJI, while a full charge takes a claimed 50 minutes.
A multi-functional battery case that doubles as a power bank can charge up to three spare batteries at a time.
Quick, easy and versatile mounting options
The Action 4 mounts using DJI’s existing magnetic mounting system.
This is claimed to make it quicker and easier to switch mounts on the go than a thumbwheel mount (as used by GoPro).
It also means the camera accommodates native vertical video because it can be switched from landscape to portrait orientation easily.
There is a cage mount for the camera to provide extra protection. This is also used to mount DJI’s wireless microphone setup, which is sold separately.
The Action 4 features built-in noise reduction and the wireless microphone opens up more options for vlogging or improving your POV audio quality.
The Action 4 retains the dual full-colour touchscreens, enabling you to not only view and frame your footage from either side of the camera, but adjust the settings too – something you can’t do with other action cameras.
