It comes with the following accessories in the box:
Design and Build
Upon first inspection, the Osmo Action 4 looks identical to its predecessor, the Action 3, a design decision that many will appreciate. This means Action 3 accessories like TPU mounts, batteries, and ND filters are fully compatible. The magnetic mounting system remains unchanged, ensuring swift and secure attachment.
The camera measures 70 x 44 x 31.8mm and weighs in at 145 grams (battery included). The battery on its own is 33.5g.
The layout is identical to the Action 3. The 2.25-inch color touch screen at the back boasts a 640x360px resolution. The ON/OFF button and the USB-C connector hatch are on the left, while the right houses the removable battery and micro SD card. The shutter button is located on top.
The real difference between the Action 3 and 4 revolves around the updated image sensor.
New and Improved Sensor
The highlight of the Osmo Action 4 is undoubtedly its new imaging system. It’s a 1/1.3 inch sensor, a popular size DJI is leaning into lately. In fact, it’s the same sensor used on the latest DJI Air 3 camera drone.
This camera promises impressive dynamic range during the day, as well as reduced digital noise in lowlight conditions thanks to its backside illuminated stack sensor. I noticed an improvement in dynamic range when switching from the Osmo Action 3 to the Action 4. This is particularly important in FPV shooting where transitioning between varied lighting is frequent. The wide-angle lens does mean that in direct light, lens flares are unavoidable, but that’s a common drawback in many cameras.
With capabilities like 10-bit color, flat color d-log m and up to 4k 120FPS footage, the video quality is sharp and vivid. The in-camera stabilization, Rocksteady, works really well, but if you prefer post-editing stabilization, you can turn off Rocksteady and utilize Gyroflow. Action 3 doesn’t support Gyroflow, and that’s a good reason to get the 4 over the 3 if you are a fan of Gyroflow.
Frame Rates & Resolution
The Osmo Action 4 can record at a maximum resolution of 4K in 4:3 (3840 x 2880 pixels, this is less than the 4096 x 3072 pixels of the Osmo Action 3), up to 60fps. Maximum bitrate for 4K 60fps is 130Mbps. There’s no 5k or 6k supports yet, however, the 4K 120fps does deliver stunning slow-motion shots (but only in 16:9, 3840 x 2160 pixels).
Flat color mode is available on the Action 4 (D-Log M), which shoots flat for color correction and color grading in post. Note that flat color is different on the Action3 which was D-Cinelike.
The fully colored front display also functions as a touchscreen. Not only does it make for quick settings adjustments, but it’s also perfect for vloggers and self-shooters to frame their shots.
The built-in microphone on the Osmo Action 4 is commendable. Even with the wind reduction turned off, it managed to capture clear audio. This makes it ideal choice for vlogging and holiday, or for every day activities.
The Osmo Action 4 is waterproof up to 16 meters without the need for an additional accessory, giving it an edge over many other action cameras.
The Osmo Action 4 battery has the same look and specs as the Osmo Action 3, and they’re compatible. The battery life is impressive, allowing up to 160 minutes of recording in a full charge. Overheating is a non-issue, especially when used on FPV drones.
Conclusion: GoPro 12 vs Action 4
The Action 4 might provide better night performance due to its larger image sensor, but the GoPro Hero 12 remains the superior camera in my opinion. It offers better image quality such clarity and color science. Also the GoPro offers unique features such as higher 5.3k 60fps resolution and 8:7 aspect ratio which is more flexible for social media.

Both the GoPro Hero 12 and Osmo Action 4 are great choices, you won’t go wrong with either. For professional, I would lean towards the GoPro due to it’s superior image quality. For hobbyists, for me the Action 4 image quality is good enough.
For those who already own an Action 3, there are not enough improvements to justify an upgrade in my opinion, unless you’re chasing the absolute best in image quality in the DJI lineup.
