Capture fast movement, changing landscapes, and first-person perspectives with the DJI Osmo Action 4 Essential Combo. Its compact camera body combines a 1/1.3 inch CMOS sensor, 4K recording up to 120fps, and a 155-degree field of view for immersive footage during travel, cycling, water activities, and outdoor adventures.
Detailed Imaging in Changing Light
The large sensor, f/2.8 aperture, and 2.4 μm equivalent pixel size support detailed footage from bright daylight into dimmer environments. A 10-bit D-Log M color mode records a wider range of tones for creators who want greater flexibility during post-production. The camera also captures still images at up to 3648 by 2736 resolution.
Stabilized Horizontal and Vertical Video
RockSteady 3.0 and RockSteady 3.0+ help reduce camera shake during active recording. HorizonBalancing corrects horizontal tilt at supported resolutions, while HorizonSteady keeps footage level through full camera rotation. The magnetic quick release system makes it easier to change mounting positions, and the horizontal and vertical protective frame supports native vertical content.
Ready for Water, Cold, and Fast Control
The camera is waterproof to 18 meters without an additional case and operates in temperatures from minus 20 to 45 degrees C. Front and rear full-color touchscreens let users frame shots, change settings, and review footage from either side. Pre-Rec can preserve up to 60 seconds before the record button is pressed, helping capture unpredictable moments.
