The DJI Osmo Action 1 was DJI's first dedicated action camera, released in May 2019. It was notable for a few key features that made it competitive in the market, particularly against the established GoPro line:
Key Features and Specifications:
 * Dual Color Screens: A major highlight was its dual-screen design:
   * A 2.25-inch touchscreen on the back for viewing and control.
   * A 1.4-inch color screen on the front, which was revolutionary at the time for effortless vlogging and framing selfies.
 * RockSteady Stabilization: It featured DJI's Electronic Image Stabilization (EIS) technology, called RockSteady, which combined EIS with complex algorithms to deliver smooth, shake-free footage. It could shoot 4\text{K}/60\text{fps} video with RockSteady enabled (with a slight crop).
 * Video Quality:
   * Records up to 4\text{K} at 60\text{fps} at 100\text{Mbps}.
   * Can record HDR video at 4\text{K}/30\text{fps} (though without RockSteady stabilization).
   * Offers 8\text{x} slow motion at 1080\text{p}/240\text{fps}.
 * Sensor and Photo:
   * 1/2.3-inch CMOS sensor with 12\text{MP} effective pixels.
   * Can capture 12\text{MP} photos in JPEG/JPEG+DNG (RAW).
 * Durability:
   * Waterproof down to 11 meters (36 feet) without a separate case.
   * Operable in temperatures as low as -10^\circ\text{C} (14^\circ\text{F}).
   * Features a removable and replaceable protective lens cap.
 * Usability:
   * Quick Switch (QS) Button: Allows rapid cycling between modes and custom presets.
   * SnapShot: Allows the user to power on and begin recording in under two seconds with a press of the shutter button.
   * Voice Control for hands-free operation.
The Osmo Action 1 laid the groundwork for DJI's action camera line and was widely praised for its dual-screen innovation and excellent stabilization for its generation. Later models, like the Action 2, Action 3, and Action 4, built upon this foundation with improvements in sensor size, battery life, low-light performance, stabilization (like HorizonSteady), and modular design.
