Is the Osmo Action 4 worth it over the Action 3?

Yes if low-light video matters to you. The Action 4's larger sensor and better dynamic range are the main gains; otherwise the two are close in design and mounts.

How does it compare with a GoPro Hero?

It matches GoPro on stabilization and waterproofing and often beats it in low light. GoPro models generally offer higher frame rates and more photo resolution, while DJI's magnetic mount is quicker to swap.

How long can it record on one battery?

Expect roughly an hour or more at 4K/30 and noticeably less at 4K/120 or in cold conditions. Carrying a spare battery is sensible for full days out.

Does it need a waterproof case?

No for swimming and snorkeling, since it is rated waterproof to 18 m. A housing is only needed for deeper diving or to protect the lens in heavy surf.

What comes in the Standard Combo?

The camera, one battery, a curved adhesive mount, a quick-release adapter and a USB-C cable. A microSD card is not included, so buy one rated for 4K write speeds.

Can I use it as a webcam or for live streaming?

Yes. It supports USB webcam output and wireless streaming through the DJI Mimo app, which makes it usable for calls and live video.

Our take on the DJI Osmo Action 4

The Osmo Action 4 is DJI's rugged action camera, built around a 1/1.3-inch sensor that shoots 4K at up to 120fps and handles low light better than most rivals in its class. It is waterproof to 18 meters without a case, has dual touchscreens for vlogging and framing, and uses magnetic mounts that swap between accessories quickly. Reviewers like the stabilization and color, but some find the menu system fiddly and the photo quality modest next to its video. It suits riders, travelers and snorkelers who want one tough camera rather than a dedicated vlogging or cinema rig.
