Overview of the DJI Osmo Action 2

DJI Osmo Action 2☆☆☆☆☆★★★★★DJI Osmo Action 2
DJI's modular action camera with 4K video
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

Overview of the DJI Osmo Nano

DJI Osmo Nano☆☆☆☆☆★★★★★DJI Osmo Nano
DJI's latest wearable action camera
The DJI Osmo Nano is DJI's latest wearable action camera and offers incredible 4K120fps performance in a minute package. With it's small size, you can clip it to a cap, wear it on a headband or on your clothes with a magnetic necklace for first person footage. It has a modular design and attaches to the "Vision Dock" which features a touchscreen as well as extra battery and storage.
  • Pros
  • 4K120fps footage
  • Wearable
  • SuperNight Mode for low light
  • Great battery life for the size
  • Cons
  • Restricted to internal storage without dock
  • Vision Dock is only splashproof

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 Action 2 and Osmo Nano have similar battery capacities. Neither camera has a removable battery. The Osmo Nano offers a much larger battery extension capacity.

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

Both cameras have built-in storage. Both the Action 2 and the Osmo Nano support SD cards. The Osmo Nano supports a lot more storage than the Action 2.

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 Action 2 is a slightly smaller camera. Both the Action 2 and the Osmo Nano have similar weights.

Weight

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

Both the Action 2 and the Osmo Nano are waterproof to 33ft / 10m. Both cameras have the same maximum usage temperature.

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.

Camera and sensor technology

The Osmo Nano features a much higher resolution. The field of view of the Action 2 is a little better than the Osmo Nano's. The Action 2 has a slightly better video bit rate than the Osmo Nano.

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.

Camera settings

The Osmo Nano's 100-25600 ISO range is far superior to Action 2's. Both cameras have the same exposure compensation adjustments.

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