Packing a new 1/1.3-inch sensor, the DJI Osmo Action 4 captures excellent video, especially in low light. It comes with DJI's usual features, such as RockSteady 3.0 and HorizonSteady, and can shoot up to 4K/120fps footage.

Unlike the modular DJI Osmo Action 2, the Action 4 looks similar to the Action 3. That means the same front touchscreen, and a large circular lens. It also keeps the same magnetic mounts system. This allows you to easily attach it to a selfie stick, or a bike or helmet mount. You can also quickly switch between the landscape or the portrait mode mount if you use the bundled case. The camera is waterproof up to 18m, though I didn't test this that much apart from a quick dip into a basin.

As mentioned, the Action 4 features a new 1/1.3-inch sensor, and you can go from standard 1080p to 2.7K or 4K videos. All three solutions can shoot from 24fps to 60fps, while 1080p can go up to 240fps. The 2.7K and 4K cap out at 120fps for slow motion footage. If you're taking photos, it's 10MP max. For HorizonSteady image stabilisation, the camera can only do it for resolutions below 4K, and with a frame rate of 60fps and below. HorizonBalancing, which keeps video stable up to a 45-degree tilt, works on all resolutions as long as it's 60fps or below. Otherwise, RockSteady and RockSteady+ will work for all resolution and frame rate types.

Video quality is great, especially if you're outdoors with plenty of natural light. Things look sharp, and colours look vibrant. Low-light performance is good, too. In places such as the dimly-lit SEA Aquarium, I was able to make out plenty of detail. Sure, it doesn't look as great as daytime shots, but it looks brighter than I expected. There's obviously some graininess, but I can live with that. DJI rates the battery at up to 160 minutes at 1080p. I was able to shoot for quite a bit without needing a charge. My Adventure Combo set came with the Action Battery Case, which lets me charge three batteries at once, while also serving as a portable USB power bank.
At S$549 for the Standard Combo and S$649 for the Action Combo, the DJI Osmo Action 4 is a worthy purchase for thrill seekers who want to capture the moment. Get the Action Combo if you can spare the cash, as it comes with a bunch of accessories you will need, such as a selfie stick. Get from Shopee, Amazon SG, or Lazada.
