What’s Changed? The DJI OM 4 Smartphone Gimbal retains most of the features its predecessor the Osmo Mobile 3 and before it the Osmo Mobile 2 with a few mount changes. Mobile devices now attach to a magnetic clamp that snaps into place on the gimbal head. The grip has been slightly altered to a more comfortable 15-degree angle.

Extended Run Time. The internal battery powers the Osmo Mobile 4 for up to fifteen hours, which is triple the time of the original Osmo Mobile. On top of that, you can use the gimbal’s USB port to charge your phone. This all gives you the freedom to live stream or shoot time-lapses without worry.

Wide Ranges of Operation. The OM4 offers the same total tilt ranges, total pan ranges, and portrait-orientation support as the previous model.

ActiveTrack. The gimbal’s ActiveTrack function allows you to select a portion of the screen, lock on to it, and track the camera’s movement to follow the subject you selected.

Gimbal Configurations. The gimbal can be used in Landscape, Portrait, Underslung, or Flashlight Mode. Underslung mode allows for low-angle shots, Flashlight mode works with the entire unit in a more horizontal configuration, while Landscape and Portrait modes allow you to adapt the phone’s orientation.

Shooting Styles. You can add pans and tilts to time-lapse shots—no special equipment required. It’s as simple as selecting the position where the camera movement will start and then where you want it to stop. If you want to take an epic panoramic image, the OM 4 can stitch one together for you from nine separate shots.

Additional Modes. The DJI MIMO app gives you access to numerous shooting modes, including Time-Lapse, Motion Time-Lapse, Hyperlapse, Panorama, Long Exposure, and LightTrail.
