Overview of the DJI Osmo Action 2

DJI'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 i3 vs the Action 2
Quick links:
Video performance

Stabilization
RockSteady 2.0
Why it matters:
A high resolution will give you crisp footage but also allow you to reframe your video without losing too much quality. A higher framerate (fps) will result in smoother video and is important when filming action scenes or fast moving subjects. Image stabilization is a crucial feature for an action camera, as it removes camera shake, vibrations, rotation and other movements that deteriorate your final footage.
Battery life
The i3 offers a slightly better 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 removable batteries allows battery swapping on the go which further extends your runtime.
Storage
Only the Action 2 features built-in storage. Both the i3 and the Action 2 support SD cards. The Action 2 supports a lot more storage than the i3.

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.
Weight and size
The i3 is a slightly smaller camera. The i3 weighs a little less than 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 difficult or uncomfortable to film with. Weight is even more crucial for certain sports like road cycling or running.
Waterproofing and usage conditions
The Action 2 is a lot more waterproof when using a diving case.

Why it matters:
Most action cameras are waterproof for accidental splashing or use above water, but if you plan on Snorkeling or Scuba Diving, we recommend choosing a camera which offers a diving case and always using it for underwater footage. If you plan on filming Snowboarding, Skiing or other wintersports in extremely cold conditions, you should pick a camera that is rated for those temperatures, most cameras are only rated down to 14°F / -10°C. Many action cameras are prone to overheating, even in ordinary conditions, so if you plan on filming in hot environments, you should choose a camera that can function at high temperatures.

Video bite rate

Why it matters:
A higher amount of pixels will offer better quality footage and higher resolution photos. A higher field of view means that the camera captures over a wider angle and therefore more action can be seen in the final footage. Some cameras require accessories to enable the maximum FOV. A higher bitrate at a similar resolution will offer higher quality video.

Why these settings matter:
The ISO range and exposure compensation settings will mostly allow you to tweak your action camera for low light situations.
