Capture steady, high-definition footage in virtually any scenario with the Osmo Action 4 Camera Standard Combo from DJI. The Osmo Action 4 features many of the same features as its predecessor, like dual screens, RockSteady and HorizonSteady stabilization systems, and a waterproof camera body. A slightly bigger sensor with a higher MP count, a new 10-bit D-Log M color mode, and an upgraded microSD slot capable of supporting larger card sizes make up the Action 4’s improved design.
High-Definition Video with a Wide Dynamic Range
The camera features a 1/1.3″ sensor to record up to UHD 4K120 video and capture experiences in dynamic, smooth detail. A super-wide 155° FOV ensures all the action is in the frame. 10-bit D-Log M color mode provides you with over one billion colors and a wider dynamic range for vivid footage.
Color Temperature Calibration
The Action 4’s colour temperature sensor intelligently adjusts white balance and auto-exposure for highly accurate colours, even in complex lighting environments like when scuba or free diving deep below the surface. Sync with the DJI Mimo app for improved detail rendering underwater.
RockSteady 3.0
An intelligent stabilization algorithm eliminates camera shakes in all directions to ensure your high-adrenaline mountain biking or skiing shots maintain smooth movements. It supports use while recording at up to 4K120, providing a stable and immersive first-person perspective.
HorizonSteady and HorizonBalancing
This smart stabilization feature helps to eliminate camera shake in all directions, and even horizontally corrects tilt at any angle in 2.7K60 video. That means footage can remain horizontally level, even through heavy bumps and 360° rotations. In addition, you can activate HorizonBalancing, which corrects the tilt horizontally within ±45° and supports recording stable 4K60 videos.
Efficient Shooting Configurations
The magnetic quick-release design of the Action 4 allows you to easily switch things up when needed. Detach and switch between different mounts and accessories. The horizontal-vertical protective frame lets you natively shoot vertical video for social media platforms.
Custom Modes and Quick-Switch Button
Use features like SnapShot to ensure you never miss a moment. Save frequently used settings to the five built-in shortcuts to switch modes on the fly using the quick-switch button or voice prompts.
Voice Prompt and Voice Control
Intuitive control, even if you can’t see the screens. Short press the Quick Switch button, and the camera will voice broadcast the current shooting mode. Even if the camera is installed on a helmet or other hard-to-see location, you can accurately select the required mode and be confident you’ll never miss the moment you want to record. You can even add up to five sets of custom parameters to the shooting mode list. Remotely control your camera with just your voice. Ideal for scenarios where your hands are busy, the Action 4 recognizes voice commands with a high recognition rate, letting you stay locked into the moment.
