Sealing depth, mount ecosystem and how long it records before it stops · review
A 1/1.3-inch sensor makes the Osmo Action 4 the low-light pick of this shelf, with 4K at 120 fps, 10-bit color, waterproofing to 59 feet without a case and magnetic quick-release mounts.
Most action cameras use sensors around 1/2.3 inch or smaller. The Osmo Action 4 uses a 1/1.3-inch sensor with 2.4 μm pixels, and DJI builds its pitch around low light. In practice, this is the camera on this shelf most likely to keep a sunset or a dim room clean.
It is rated waterproof to 18 meters (59 feet) on its own, which covers swimming, surfing and snorkeling. The 1770 mAh battery is rated down to -20°C (-4°F), a useful promise for skiing.
The magnetic quick-release system clips the camera on and off its mounts and swings it to vertical. It is faster than the screw-and-finger mounts used by most budget cameras.
DJI lists Pre-Rec, which keeps the 5 to 60 seconds before you press record, and Highlight markers for faster editing. The camera also pairs directly with a DJI Mic 2 or Mic Mini transmitter.

No. DJI rates the camera itself to 18 meters (59 feet). A housing is only needed for deeper diving.
A flat color profile that keeps more shadow and highlight detail for editing. It is paired with 10-bit recording, which gives smoother gradients when you adjust color.
DJI says the Essential Combo drops the curved adhesive base, while the Adventure Combo adds a 1.5 m extension rod, two extra batteries and a battery case. The Standard Combo sits between them.
At $239, it is the 5 cheapest of the 5 models in this category published here.
8.3/ 10
The best image on this shelf, especially when the light drops, and the only one sealed to 59 feet without a case. Pay for it if footage quality matters more than price.
