Osmo Action 4 has a larger 1/1.3-inch image sensor than its predecessor. With a single pixel equivalent size of 2.4μm, Osmo Action 4 delivers footage with minimal noise in both moving and low-light scenes. D-Log M is designed for professional videography. It enhances the dynamic range in high-contrast or multi-colored environments (such as blooming gardens). It enables greater flexibility in color grading during post-editing, capturing the scene's essence. 10-bit color depth enables smoother color transition with no discrete step changes. The 155° ultra wide-angle also captures an expansive view of your surroundings during movement, creating an intense visual impact and immersing you in vast landscapes when recording scenery.
