DJI Action 2  Camera Review

The DJI Action 2 is incredibly portable. The camera is tiny and lightweight, taking up less than half the space of its predecessor, the DJI Osmo Action, and other typical action cameras. Even with a module attached, it's still very compact. With the Front Touchscreen module attached, the camera's dimensions are:

• Height: 3.1" (7.8cm)
• Width: 1.5" (3.91cm)
• Depth: 1.0" (2.46cm)
• Volume: 4.6 in³ (75.3cm³)
• Weight: 0.26 lbs (0.12kg)

Finally, with both the module and the Magnetic Protective Case, the dimensions are:

• Height: 3.4" (8.6cm)
• Width: 1.7" (4.3cm)
• Depth: 1.0" (2.7cm)
• Volume: 6.0 in³ (97.7cm³)
• Weight: 0.31 lbs (0.14kg)

Build quality is okay. The camera itself feels solid and is made of aluminum alloy. The material feels sturdy, but while it supposedly disperses heat away from the camera's internals, it also makes the camera very hot to the touch, which is a big downside. Even when simply scrolling through the menus while charging the camera via USB, we measured a temperature of 49.8ºC (121.6°F), which skirts the line for the safe handling of metal objects. When recording 4k 60 fps video, the camera eventually reached a temperature of 69ºC (156.2°F).

DJI has acknowledged the overheating issues of the camera and released a Magnetic Protective Case in response, which is meant to "reduce surface temperature" and provide better heat management. In practice, it lets the camera record longer and reach even higher temperatures. With the case on, we recorded a 4k video clip at 120 fps, after which the camera reached a concerningly hot temperature of 74.5ºC (166.1°F). While the Magnetic Protective Case, which is made of a heat-resistant polymer, does provide some protection for your fingers, the camera still gets dangerously hot, and it can be especially unsafe when recording handheld or using the Magnetic Lanyard, which brings the camera close to your skin.

Even setting that aside, the camera uses very powerful magnets with clips to attach the different modules. While that creates a sturdy connection between parts, we found that the camera scratches easily, and the coating begins to wear off quickly in high-friction areas around the clips and expansion port. DJI also warns that you should keep the magnetic parts of the camera away from devices that can be damaged by them, including pacemakers and credit cards.

The camera is waterproof, but that comes with some caveats. The camera unit has an IP68 rating, meaning it's rated for immersion in over 1m of water and is dust-tight. DJI advertises it to be waterproof down to 10m. However, they also caution against using it in hot springs or hot tubs or during activities like cliff diving that involve high impact with water. Additionally, neither the Power Module nor the Front Touchscreen Module are waterproof. To use those underwater, you need to purchase an additional waterproof case from DJI, which allows you to submerge the whole unit underwater down to 60m.

Though the DJI Action 2 is primarily meant for mounting to various accessories, like the Magnetic Lanyard or attached to a tripod with the Magnetic Ball-Joint adapter, the Front Touchscreen module also allows it to be used handheld for selfies and vlogs. However, because of its small size, the camera isn't the most comfortable to hold, especially if you have larger hands. The size, combined with the placement of the shutter/record button, makes it hard to press naturally. The magnets that connect the camera unit to the different modules are also very strong and could easily pinch you if you aren't careful.

That said, the biggest issue for comfort is excessive overheating, which we detailed in the Build Quality section above.

The camera unit has a very small back screen, which isn't very useful for monitoring recording because of its size. With the Front Touchscreen module attached, you get an additional front-facing screen that you can use to monitor yourself live when recording in a selfie position. However, it's just as small as the camera unit screen. Neither screen gets overly bright, but they're decent for combatting glare.

The camera doesn't have any physical buttons aside from the power and record buttons, so the touchscreen is used to navigate the menus and adjust settings. However, it sometimes fails to register an input or swipe motion, and at other times, it's easy to accidentally swipe to a menu or setting you didn't mean to. Usefully, you can only have one touchscreen active at a time, so if you're shooting in selfie mode, the back screen will automatically lock, and vice versa.

The user interface is great, considering how small a display area there is to work with. The settings are spread out in different menus that you pull up through different directional swipes. For instance, swiping down brings you to the general settings page, which you can see here while swiping left brings you to shooting settings. Despite the size, the menus are well-organized and quite easy to navigate.

There's also the DJI Mimo app, which lets you control the camera from your phone. Naturally, it's a lot easier to see and access settings through the app, which looks like this. The app includes a 'Pro' mode that gives you control over all the different settings. Unfortunately, there's no in-app help or guide function to explain features or settings in more detail.

Battery life is terrible. When recording with the camera unit on its own, it can only capture under half an hour of footage at its highest quality settings. That's far short of other action cameras, including the original DJI Osmo Action, as well as the GoPro HERO10 Black. Since we bought the Dual-Screen Combo, we also tested the camera's battery life with the Front Touchscreen module attached, which supplies some extra power to the camera, and recorded about 64 minutes of footage on a full charge. However, the camera overheated five times during recording. Note that you can also purchase the camera with a Power module that's advertised to boost the battery life to a slightly greater degree than the Front Touchscreen module (180 minutes vs. 160 minutes, respectively, according to DJI).

It's worth noting that the camera unit itself doesn't have a USB-C port. You can charge it via USB, but only with one of the modules attached. That also means there's no way to charge the camera if you happen to lose the module.

Unlike the DJI Osmo Action, there's no burst mode, but these cameras aren't meant for continuous shooting. You can only capture one photo at a time, with about a 1s delay as the camera records the image to memory before you can take another.

We managed to get stable images at fairly slow shutter speeds, but the camera doesn't have any image stabilization in photo mode. The clarity of your photos at slower shutter speeds will depend heavily on how steady your hands are.

The DJI Action 2 has a few different resolution options, including 4k, 2.7k, and 1080p, though it can only shoot 1080p footage in a 16:9 aspect ratio, whereas 4k and 2.7k can be recorded in 16:9 or 4:3. The standard 1080p setting downsamples footage from 4k; there's also a '1080p Power Reserve' mode that downsamples from 2.3k, so quality is slightly worse, but it doesn't drain the battery as much.

You can adjust the camera's field of view between Standard, Wide, and Ultra Wide.

In addition to standard video and slow motion modes, the camera includes a time-lapse mode with different presets for subjects like clouds, sunsets, and crowds. There's also a hyper-lapse mode for moving time-lapse footage.

Finally, there are several different stabilization modes. 'RockSteady' and 'Steady' are the standard stabilization modes that reduce the amount of camera shake in your footage to different degrees. 'Steady' mode incurs a 1.2x crop, while the more aggressive 'RockSteady' stabilization incurs a 1.5x crop. Additionally, there's a 'HorizonBalancing' mode that levels the horizon when rotating the camera up to a 45º angle. You can see how it works here. It also incurs a 1.5x crop. Last, there's 'HorizonSteady', which keeps the horizon level no matter how you move the camera. This mode is only available in 1080p or 2.7k and incurs a 1.75x crop. You can see it in action here.

Note: The camera unit has just one microphone, while the Front Touchscreen module adds another three mics. We recorded the sample above using just the camera unit.

You can set the camera to pick up audio from different directions (front, front and back, or all). However, we didn't notice much, if any, difference when adjusting these settings.

There's also an 'Audio Zoom' feature that amplifies the audio as the camera zooms in towards the source of the sound. You can see that in action here.

The DJI Action 2 has plenty of frame rate options in 4k, including a dedicated Slow Motion mode for 120 fps recording. That said, there's only one playback speed option, 4x slow-mo. Another thing to note is that live view on the Front Touchscreen module is disabled when recording at 120 fps in the Slow Motion mode. Instead, you simply get a resolution and frame rate display, with a red recording indicator, as seen here.

4k internal recording capability is just okay. While the camera doesn't impose a recording time limit, it's also limited by its short battery life, so you can't do any lengthy recording without an external power bank anyway. The camera also overheats very easily, which can interrupt your recording.

The DJI Action 2 doesn't have an autofocus system because its narrow aperture creates a very deep depth of field that keeps the entire scene in focus.

4k video quality is poor relative to larger-sensor cameras but performs on par for an action cam. Because of the camera's small sensor, it isn't well-suited to shooting indoors or in low light, where video looks very grainy and lacking in detail. It's meant for shooting outdoors in bright lighting conditions. However, it does fare a little better overall than the original DJI Osmo Action, which uses an even smaller sensor.

Slanting from rolling shutter is minimal when panning the camera. Even if you change the field of view, the angle of distortion stays the same.

The DJI Action 2 has plenty of frame rate options in 1080p. There's a dedicated Slow Motion mode that lets you record at either 240 fps (8x slow motion) or 120 fps (4x slow motion).

FHD internal recording is pretty good. However, while it doesn't impose a recording time limit, the camera is prone to overheating and has a limited battery life, which can cut your recording time short.

The DJI Action 2 doesn't have an autofocus system because its narrow aperture creates a very deep depth of field that keeps the entire scene in focus.

Video quality in 1080p is bad overall but not far from most action cameras. The camera is meant for brightly lit outdoor recording and isn't really suitable for recording indoors or in low light, resulting in very grainy footage with muddy details. In '1080p Power Reserve' mode, the video quality is slightly worse, as the camera downsamples from 2.3k rather than from 4k, as it does in the regular 1080p setting. You can see a test scene extract for the '1080p Power Reserve' mode here.

Slanting from rolling shutter is minimal when panning the camera. Even if you change the field of view, the angle of distortion stays the same.

The camera unit on its own relies on built-in memory, with a capacity of 32 GB. However, both the Front Touchscreen module and Power module include a microSD card slot for added storage.

The USB-C port is also only available when using one of the modules. The camera unit on its own doesn't have any inputs/outputs, which means you can only charge the camera with one of the modules attached.
