Launched in August 2023, the DJI Osmo Action 4 takes up where the third generation left off. The main new features include improved water-resistance to a depth of 18 meters, and above all the integration of a brand-new 1/1.3-inch sensor. Although resolution remains 4K at 120 fps, this larger sensor considerably improves image quality, whether in daylight or in low-light conditions. Want to find out more?
