DJI Delivers Upgrades to Its Osmo Action Sports Video Cam

DJI’s Osmo Action 4 sports video camera promises “remarkable low-light performance” thanks to a larger 1/1.3-inch image sensor that captures more light through an utrawide f/2.8 aperture 155-degree lens. At $399, the Action 4 retails for about $70 more than the Action 3 but offers improvements including the ability to shoot in 10-bit D-Log M format for higher dynamic range that allows for greater color-correction flexibility in the editing room. The Action 4 also supports greater storage of up to 512GB using a required microSD card (the camera has no internal storage).

While the Action 4’s sensor is larger than the Action 3’s offering, “both models capture 4K footage at up to 120 frames per second max,” writes The Verge. That makes the Action 4 comparable to “GoPro’s current flagship Hero 11 Black camera, which can match that and support up to 5.3K 60fps footage.”

The GoPro “has had a small feature advantage: a built-in GPS,” according to The Verge, which says the DJI “has a new accessory that can inject GPS metadata into the video files on the Action 4.”

The $79 Osmo Action GPS Bluetooth Remote Controller “straps to your wrist or handlebar so you can remotely start or stop recording, change between modes, or glance at the camera’s status on its small screen.”

The Action 4 also has RockSteady 3.0 Plus, an upgraded digital stabilization system, and features HorizonSteady, which locks the tilt mechanism to keep the horizon line straight during recording, “even if the camera does a barrel roll,” The Verge suggests.

DJI’s InvisiStick mode, which makes the 1.5-meter selfie stick invisible, has been improved for use in more complex backgrounds. And the Action 4 has better waterproofing that lets you submerge the camera up to 18 meters (compared to 16 meters for the Action 3).

A diving case eliminates that limitation, and the DJI press release also details voice control, seamless AI editing with the company’s LightCut app, and more.

Overall, the Action 4’s 1/1.3-inch sensor is the same one on DJI’s “Mavic 3 Pro, the Mini 3 Pro and Air 3 drones,” Engadget reports. The larger sensor and D-Log are the main differences. The Action 4’s design is identical to that of the Action 3 and features the same 1770 mWh battery “with 150 minutes of recording time — and just 18 minutes of charging time to get the battery to 80 percent.”
