The gap between this and the GoPro shows up after the sun drops, not at noon. DJI's 1/1.3-inch sensor keeps color and detail in shade and at dusk, where the smaller chips in the budget cameras start to smear. Add 4K at 120fps and a 155-degree field of view and you get the most forgiving footage in this group to work with afterward — more of the scene in frame, and more of it usable when the light is not on your side.
Stabilization is what makes it our default for sport. RockSteady takes the chatter out of bar and helmet mounts, and HorizonBalancing keeps the frame level through a lean, which is the difference between footage people watch and footage they scroll past. We kept coming back to the magnetic quick release, too: bar to helmet to a vertical shot takes seconds, with no thumbscrew to hunt for in the dirt. The front screen is full color and touch-sensitive, so framing yourself is not a guess.
The trade is resolution. The GoPro shoots 5.3K to this camera's 4K, which matters if you like to crop into a wide shot or pull stills out of video. Everywhere else the numbers favor DJI: the 1770mAh battery is rated for well over two hours and keeps working down to minus 4 degrees Fahrenheit, the figure that matters on a ski day rather than a beach one.
Pros
- Big sensor keeps color at dusk
- RockSteady and horizon lock steady fast mounts
- Magnetic mount swaps in seconds
- Cold-rated battery suits ski days
Cons
- No memory card in the box
- App pairing can take a few tries
Our default for sport: the steadiest footage of the group, a sensor that still works at dusk, and no housing to fumble with before you jump in.
