The Osmo Action is loaded with a wide range of high-resolution features within its tiny frame. It supports up to 4K60 HDR video recording, captures slow-motion video at rates up to 1080p240, utilizes DJI's RockSteady Electronic Image Stabilization (EIS), and can also operate in time-lapse and hyperlapse modes. Still images can be captured in up to 12MP resolution in raw or JPG format, and when you rotate the camera 90° when taking stills, it will automatically change to Portrait mode. When recording in 4K30 format you can take advantage of the camera's High Dynamic Range (HDR) support, and it features a wide dynamic range to ease transitions between light and dark. All stills and video are saved to a microSD card in a slot that supports microSD/SDHC/SDXC cards with a minimum of 30 Mb/s write speed and a maximum 256GB capacity.
This pocket-sized camera somehow manages to fit not only one, but two displays on its tiny frame. The back 2.25" 16:9 display has a crisp 640 x 360 resolution that covers the entire back of the unit. The front 1.4" 320 x 320 square display sits right next to the lens and allows you to preview your image while you're in the action or taking selfies. Both displays feature touchscreen control, saving precious housing space from those pesky old-fashioned buttons. In order to avoid accidentally pressing anything on the touchscreen while shooting, there is a handy screen locking switch on the side of the housing. The Osmo Action can also be controlled via Bluetooth or Wi-Fi from an iOS or Android smartphone using the DJI Mimo app.
Additional bonus features include a maximum ISO of 3200, dewarp mode to remove wide-angle FOV bending, custom setting modes for quick access, dual microphones, dual speakers, and it is powered by a removable LiPo battery. The Osmo Action is waterproof to 36' deep, so you can surf, snorkel, and swim safely with your camera for up to 30-minute intervals. For even deeper underwater activities you can take the Osmo Action down to 197' with a separately available waterproof housing. Its original housing is so durable that it can easily withstand drops from up to 5' high.
Accessories in the box include a mounting frame, a USB Type-C cable, a quick release base, a flat adhesive mount, a curved adhesive mount, and a connector screw for connecting the mounting frame to a compatible action mount.
