Design

The DJI Action 2 camera system has a modular design comprised of “blocks”. The main block is about 1.5 x 1.5 x 1 inch and is the “brains” of the DJI Action 2 camera itself. This block contains the camera lens on the front and a small 2-inch display on the back. The blocks contain magnets that allow you to easily attach different accessories. 

At launch, there are two different kits you can purchase: 

  • The Power Combo contains an add-on power bank as the 2nd block and adds about 66 minutes of recording time, as well as a USB-C port and a Micro SD card slot.
  • The Dual-Screen Combo that I’m reviewing, which includes a 2nd block with a built-in display, power bank (although only adding about 49 of recording time), USB-C port, Micro SD card slot, and additional microphones.

There’s also an interesting magnetic lanyard included that you can wear under your shirt and attach the DJI Action 2 magnetically through your shirt. This makes it great for recording your hikes, bike rides, etc without needing to strap on a chest harness. It also makes it quick and easy to detach and reattach the camera as needed.

Performance

Both pictures and videos recorded with this camera are impressive, especially considering the DJI Action 2 is so small! Photos can be captured with a resolution of up to 12MP and exported in JPG or RAW format. Videos can be recorded up to 4K at 120FPS.  Both video and picture quality is great: even when shooting directly into the sun, the camera still captures a good amount of detail in the shadows for a well-balanced photo.

DJI has two modes of video stabilization. The “Rocksteady” mode does a surprisingly good job of smoothing out videos while walking around, almost as if I was using a gimbal.

The second stabilization mode is “Horizonsteady” which keeps the horizon level in the distance regardless of how you rotate the camera while shooting.  I found this useful when I wanted to move the camera down to ground level and back up as I could rotate the camera around without it showing on the video recording.

There is a button on the main block and the accessory block. You can turn the camera on and off with a long press of either button and snap pictures or start/stop recording with a quick press of either button. 

Using the small 2-inch display takes some getting used to, especially if you have big fingers. You can swipe left-to-right to view your pictures, and swipe right-to-left to view picture settings.  Swiping from the middle of the screen to the left or right changes between the different modes, such as photo, video, slow motion, etc.

The DJI Action 2 only has 32GB of internal storage, with only about 22GB available out of the box. You’ll likely want to take advantage of the MicroSD card slot on either the power bank or dual-screen block. 

The DJI Action 2 also features a “webcam” mode when connected to a computer, so you can use it for video calls when you’re not out on an adventure.

I have noticed that the camera will sometimes pause operations after prolonged use due to heat. It’s only happened a couple of times to me, but I could see these becoming more of an issue during the summer season.

Battery Life

The DJI Action 2 camera can last about 30 minutes by itself. The Power Combo block adds about 66 minutes while the Dual-Screen Combo block adds about 49 minutes.

9.1Expert Score
Great

The DJI Action 2 takes great 4K videos and 12MP pictures in a tiny 1.5 x 1.5 x 1” design. Optional accessories connect magnetically and can either be used to extend battery life or add a second display. The magnetic lanyard is a genius feature for quickly attaching the camera to your chest. Limited built-in storage and battery life make this more ideal for short clips rather than long recordings.

PROs
  • Great picture quality
  • Strong stabilization performance
  • Magnetic lanyard
CONs
  • Short battery life
  • Occasional shutdowns due to heat

Setup

The unboxing process was a little confusing as the included “Quick Start” guide reminded me of sparse IKEA instructions. Part of the issue was finding all the parts: some were hidden in the shoulder bag (be sure to check the not-so-obvious pocket underneath the top of the bag for the cables) and the various black cardboard boxes. There is an unboxing video available on DJI’s website as well.

Remote Controller

As a previous owner of the DJI Spark, I’m really enjoying the improved controller on the Mavic Air 2. The antennae is built into the phone cradle, so you’re automatically extending the antennae when you put your phone in. Your phone also connects via a cable on this controller (Lightning is installed by default; the Micro USB and USB-C cables are in that hidden pocket of the shoulder bag). This leads to a much more stable connection and a much quicker setup time as you don’t need to mess with your phone’s WiFi settings to connect to the controller. Please note that there is no option to connect your phone directly to the Mavic Air 2 (you need the remote controller as a go-between).

With my DJI Spark, I would receive a “signal interference” message more often than I liked, even in rural areas away from other WiFi and Bluetooth signals.  I have yet to receive this message on the Mavic Air 2 and I’ve noticed that the live video feed is a lot smoother.

The controller is heavier than the DJI Spark’s controller, but is still comfortable to hold.  The controller also has an option to charge your phone, but it is off by default and must be enabled each time you fly (I hope this is a bug).  In the app, tap the Settings option and you’ll find the charging option under “Controller”.  Otherwise, I find my phone battery drains very fast.

Performance

Compared to the DJI Spark, the Mavic Air 2 moves a lot faster, even in Normal mode.  If you’ve used the DJI Spark in the past, you’ll want to be cautious you don’t go too fast.

While the Spark had a forward-facing sensor to prevent it from flying forward into an obstacle, the Mavic Air 2 also has sensors behind and underneath (but it could still collide with an object on either side or above it, so it’s not completely collision-proof).

The Mavic Air 2 is very stable when hovering and I have not noticed any drifting.  Of course, the outdoor wind speeds will greatly affect this, but the Mavic Air 2 seems to contend with light breezes very well.  

Camera

The DJI Spark features a 12MP camera and can record 1080p 30FPS video. The Mavic Air 2 can capture up to 48MP and can capture 4K video up to 60 FPS.  The Mavic Air 2 also had a 3-axis gimbal for smoother images stabilization compared to the Spark’s 2-axis gimbal.

The image quality is amazing and I’ve been very pleased with the results.  There are also some lens filters included for shooting in bright situations, such as sunrises or snowy landscapes on a sunny day.  The “Smart” photo settings also does a great job of creating HDR photos that would have previously required the use of shooting multiple photos in AEB mode and performing the HDR effect in a separate photo editing program. 

Like the DJI Spark, it is somewhat confusing to figure out where to retrieve your images and videos.  To get the highest quality images and videos, you need to pull the files off of your memory card (please note that a memory card is not included in the Fly More package). Yet, the memory card only has the raw footage of the Quick Shot videos and other special effects like panoramas. To get the stylized Quick Shot videos and special photos, you must render them in the app and save it to your phone’s album.  To add to the confusion, the app stores low quality “preview images” by default, and you must specifically go into the app’s “album” feature *while the drone is still powered on* in order to download the HD quality videos and images to your phone and to render the fancy photos and video features. 

Battery

There are 3 batteries total in the DJI Mavic Air 2’s Fly More package.  Each battery can get you up to 34 minutes of fly time, little more than double the 16 minute flight time of the DJI Spark.  The charger works a little differently than on the Spark: each Mavic Air 2 battery charges one-at-a-time (starting with the battery with the largest amount of existing charge) instead of simultaneously.
