Overview of the DJI Osmo Action 2
DJI Osmo Action 2DJI's wearable action camera: 4K video in a modular format
The DJI Osmo Action 2 is an extremely modular action camera which delivers incredible 4K120fps footage while still remaining wearable. Thanks to it's magnetic attachement system, you can mix and match modules to transform it to suit every use case you can imagine. It's successor, the DJI Osmo Action 3, has abandonned this modular design, so the Action 2 remains DJI's current wearable camera.
- Pros
- 4K120fps footage
- Wearable
- Lightweight
- Cons
- SD card only with extra module
- Modules are not waterproof without case
- Not freeze-proof
- Overheating issues
Comparison of the Theta X vs the Action 2

Why size and weight matter:
Weight is important for action cameras because we often mount them on helmets, or hold them at the end of a selfie stick while moving. Therefore a heavier camera can be dvifficult to use or uncomfortable. Weight is even more crucial for certain sports like road cycling or running.
Battery life
The Theta X offers a much larger battery capacity. Neither camera has a removable battery.

Why battery life matters:
Nothing worse than running out of battery just before capturing the best footage of the day! A long battery life is reassuring and convenient when shooting footage outdoors where options to charge are limited. Even the use of a power bank can be tedious or simply impossible like when filming watersports. Having removeable batteries allows battery swapping on the go which further extends your runtime.
Storage
Both cameras have built-in storage. Both the Theta X and the Action 2 support SD cards.

Why storage matters:
High quality footage can quickly take up lots of space and insufficient storage can soon be frustrating. Having a large amount of storage and the possiblity to extend it or swap SD cards while on a outing will ensure you will always be able to capture the footage you want. However, smaller, wearable action cameras often rely on built-in storage because of their small size.
