DJI Action 2 review: modular 4K/120p action camera
The DJI Action 2 is a compact modular action camera built around a tiny magnetic camera unit and optional modules for screen, battery, audio and storage. It is no longer DJI’s newest action camera, but it remains interesting if you want a very small camera for travel, POV clips, vlogging and lightweight setups.
This review explains the DJI Action 2 specifications, strengths, limits and what to check before buying one today.

What makes the DJI Action 2 different?
The Action 2 is not a normal rectangular action camera. The main camera is a tiny square module. You add the front touchscreen module, power module or mounts depending on the job. This makes it flexible, but it also means the experience depends heavily on which modules you own.
If you want the smallest possible camera unit, the design is brilliant. If you want long battery life, simple heat management and built-in everything, a newer one-piece action camera may be easier.
Video quality and stabilization
The headline feature is 4K/120p, which allows smooth slow motion in a very small package. The wide 155-degree lens is useful for action, POV and travel clips. RockSteady helps smooth handheld movement, while HorizonSteady keeps the horizon level in compatible modes.
As always with action cameras, stabilization, high frame rates and heat management are connected. The more demanding the mode, the more you should expect limits from a tiny body. For long sessions, modules and external airflow matter.
Battery life and modules
The camera unit alone is designed for short, lightweight shooting. DJI’s lab figure of about 70 minutes is based on controlled conditions and lower-demand recording, so real-world 4K use can be shorter. The front touchscreen module and power module extend recording time and add useful features such as extra screen, microphones, USB-C and microSD support.
Best uses
- Travel: tiny body, quick clips and light packing.
- Vlogging: useful with the front touchscreen module.
- POV shots: magnetic mounts make creative angles easy.
- Sports: good when you want a compact camera, but check heat and battery limits.
- Webcam or streaming: possible through USB video support.
Pros and cons
| Pros | Cons |
|---|---|
| Tiny modular camera unit | Battery life depends heavily on modules |
| 4K/120p slow motion | Small body can heat up in demanding modes |
| Wide field of view and stabilization | Some modes limit stabilization or zoom |
| Creative magnetic mounting system | Not as simple as newer one-piece action cameras |
Used buying checklist
- Check which modules are included: power module, front screen or only camera unit.
- Test USB-C charging and module connection.
- Inspect the lens cover and touchscreen for scratches.
- Check battery behavior in 4K recording.
- Confirm that mounts and magnetic accessories are included.
- Compare the price with newer DJI Osmo Action models before buying.
Verdict
The DJI Action 2 is still a clever action camera if you value modularity and a very small body. It is best for short creative clips, travel and flexible mounting. If you need long recording times, easy heat management and the latest action-camera image quality, a newer DJI Osmo Action model may be a better choice.
