Comparative table of popular action cameras.
Among the compared cameras, we have selected top models and compared the most popular and necessary parameters that you should pay attention to when choosing an action camera.
Comparison of action camera matrices
All cameras are 12-megapixel 1/2.3‑inch sensors and shoot 4K video. Osmo Action, GoPro 7 and 8 allow you to shoot 4K video up to 60 fps. And Osmo Action, unlike everyone else, also shoots HDR video.
Just like the HERO 7 and 8 Black, Xiaomi uses a 170° wide-angle lens. While this is common with most action cameras, many users oppose it due to the fisheye effect. The DJI OSMO Action Camera uses a slightly narrower 145° field of view, which results in less distorted images.
I also want to note that GoPro cameras have electronic distortion correction, the so-called linear mode, but this function is not available when shooting in 4K. In addition to the narrower field of view (FOV), the DJI action camera has distortion correction that is available even in 4K.
The Osmo Action lens, unlike the others, has a convenient filter attachment system, just screw them on instead of standard glass.
All cameras allow you to shoot in 4K at a maximum frame rate of 60 frames per second, and you can also choose between two formats: NTSC or PAL. GoPro HERO7 Black and DJI OSMO Action offer 24fps mode.
At 1080p, OSMO Action and HERO7 Black can shoot at up to 240fps.
All cameras have electronic image stabilization, which is supported by a 6‑axis gyroscope. But each of them from different brands. On GoPro HERO 7 and 8, this feature is called “Hypersmooth” and “Hypersmooth 2.0”, on DJI OSMO Action it is called “RockSteady”, Sony and Xiaomi have not named it. With these two models, electronic image stabilization is available up to shooting in 4K at 60 frames per second.
All cameras are equipped with a 12MP 4:3 sensor, so the maximum resolution is 12MP in 4:3 format. You can take pictures in .jpg or RAW format. The GoPro HERO7 and 8 Black only offer HDR photo mode, while the Osmo Action can shoot HDR video but not HDR photos.
All cameras have screens on the front and back. The front display on HERO7 and 8 Black shows only the information you need: settings, shooting time, remaining space on the memory card, selected mode, and more.
The DJI OSMO Action, on the other hand, offers a Live-View screen that acts as a mirror, which is great for selfies or vlogging.
Case, buttons, ports
The first three cameras are waterproof even without an additional housing. HERO 7 and 8 Black are protected up to 10 meters, OSMO Action up to 11m, Xiaomi and Sony are not waterproof and will need a water box to dive into the water. All cameras have a USB‑C port that can be used to connect to a computer, charge, and even connect an external microphone.
GoPro HERO 7 and 8 Black cameras allow you to use several interesting features at once. Voice control is very convenient for selfies, as there is no need to connect the camera to a smartphone or remote control. It is enough to say “GoPro take a photo”, and she will take a picture with a minimum delay. Another distinguishing feature is GPS data. The camera remembers speed, acceleration, altitude, G‑force and more, and you can display all of this right on top of the video in post-processing.
DJI OSMO Action is the only action camera that can record HDR video. With HDR, you can increase the dynamic range of your video, resulting in smooth, natural transitions between light and dark areas. This is a hugely important feature for conditions with poor lighting. Video-HDR is only available up to 30 fps and cannot be used in conjunction with RockSteady image stabilization. Just like GoPro, OSMO Action can recognize voice commands.
To sum up, each of the cameras has its own advantages.
For example, Xiaomi always offers a low price, and Sony is great at recording sound. GoPro has undeniably had a huge fan base around the world for many years.
In this regard, DJI with its Osmo Action camera is a newcomer but with significant fat pluses: firstly, it shoots HDR video, the excellent patented RockSteady electronic stabilization system, water protection up to 11 meters and a color front screen. Of the minuses of Osmo Action, a weaker battery can be distinguished, as a result of which it lasts for less shooting time and some buyers complain about worse sound recording, but this is due to the fact that the camera has excellent water protection, which imposes special requirements on the microphone.
To get rid of these disadvantages, we advise you to immediately stock up on additional batteries and an external microphone that can be connected through a special adapter.
