GoPro’s Hero 13 Black retails for $349. The DJI Osmo Action 4 Essential combo just dropped to $169, off its $199 typical price and at its record low on Amazon, making it the number one best seller in sports and action cameras at less than half the price of its most obvious rival. This deal is open to all Amazon customers with no Prime membership required.
1/1.3-inch sensor, 4K/120fps, 155° field of view
The Osmo Action 4 runs a 1/1.3-inch sensor with 2.4μm pixel size, which is significantly larger than the sensors found in most action cameras at this price point and directly responsible for the low-light performance that DJI leads with. Larger pixels capture more light per photosite, which translates to cleaner footage in dawn, dusk, and indoor conditions where smaller sensors produce grainy, noisy results. Auto white balance adjusts continuously for true-to-life color even underwater, where artificial light sources create significant color shift that fixed white balance settings cannot compensate for.
4K at 120fps opens up slow-motion at full resolution rather than requiring a drop to 1080p for high frame rate capture, and the 155° ultra-wide field of view covers the full peripheral sweep of action sports, motorcycle riding, and FPV footage without requiring an add-on lens. Three stabilization modes handle the shaking, bumping, and vibration that action footage introduces, and the magnetic quick-release system switches between mounts and shooting angles in seconds without tools.
10-bit, D-Log M, dual touchscreens, DJI OsmoAudio
10-bit color depth captures a significantly wider tonal range than the 8-bit footage most competing action cameras record, preserving subtle shades and gradients that compress or clip in lower bit-depth formats. D-Log M is a flat color profile that retains maximum dynamic range in the recorded file for color grading in post-production, which matters for anyone who edits footage rather than uploading it directly from the camera. The combination of 10-bit and D-Log M puts professional color science into a camera that retails for less than a GoPro subscription plan.
Two full-color touchscreens cover front and rear, letting you frame shots and adjust settings without removing the camera from its mount or flipping it around. DJI OsmoAudio connects directly to a DJI Mic 2 or Mic Mini transmitter for wireless audio without a separate recorder, which simplifies the gear load for vlogging and interview setups considerably. Pre-Rec captures footage from up to 60 seconds before you press the record button, ensuring that unexpected moments are never missed.
The 1,770mAh battery runs up to 160 minutes in standard conditions and remains operational at temperatures as low as -20°C, which covers winter sports and cold-weather travel that kills most action camera batteries within an hour. IP68 waterproofing handles submersion up to 18 meters without a separate housing. At $169 at its record low, the Osmo Action 4 is the number one action camera on Amazon by sales rank, available for less than half the price of a GoPro Hero 13 Black and with a sensor that outperforms it in low light.
