Product Profile

Osmo Action 4 is capable of capturing smooth video at up to 4K/120fps and offers a 155° super-wide FOV. With DJI’s latest EIS (Electronic Image Stabilization) technology, Osmo Action 4 can record super smooth footage for various sports scenes. With a 1/1.3-inch image sensor, the camera ensures low- noise footage in sports scenarios and low-light scenes with a high dynamic range or high contrast. In addition, D-Log M color mode provides a more comfortable color perception and a larger dynamic range, which is convenient for post-production color correction. Osmo Action 4 is equipped with dual touchscreens. The front touchscreen helps capture the perfect selfie, while the rear touchscreen displays the liveview of the camera.

Accessories

Osmo Action 4 is compatible with various accessories to flexibly change the position to shoot various sports scenes.
Osmo Action Curved Adhesive Base Kit
The Osmo Action Curved Adhesive Base Kit includes the following accessories.

Osmo Action Quick-Release Adapter Mount: with a magnetic design, the quick- release adapter mount can be easily attached to the camera and connected to other accessories.

|

Osmo Locking Screw: secures the Osmo Action Quick-Release Adapter Mount to the Osmo Action Curved Adhesive Base.

|

Osmo Action Curved Adhesive Base: the base forms a strong, durable, and long- lasting bond on clean and curved surfaces, ensuring secure mounting.

Press down on the camera until the clips of the quick-release adapter mount are firmly inserted into the quick-release slots on the camera, and then tighten the locking screws. Wipe the surface of the object before attaching the adhesive base. Attach and press the adhesive base down firmly, and hold for at least 10 seconds. It is recommended to wait 30 minutes before attaching the camera.

• Press down on the camera until the clips of the quick-release adapter mount are firmly inserted into the quick-release slots on the camera, and then tighten the locking screws. Press both clips of the quick-release adapter mount when removing the camera.
• Osmo Action Curved Adhesive Base can only be applied to clean curved surfaces once. DO NOT attach the curved adhesive base to surfaces that are flat, rough, powdered, peeling, covered in dust or sand, or have oil, wax, or water stains. Otherwise, the adapter mount may not be attached firmly.
• The recommended application temperature for the base is -10° to 40° C (14° to 104° F). DO NOT attach the adhesive base to a surface with a higher or lower temperature.

Osmo Action Horizontal-Vertical Protective Frame
With the Osmo Action Horizontal-Vertical Protective Frame, users can flip the camera from the horizontal to the vertical position for different shooting angles. As shown in the figure below, open the buckle of the horizontal- vertical protective frame, align and place the camera into the frame, and then close the buckle. The left side of the frame is equipped with two quick- release slots, which can be used with the Osmo Action Quick-Release Adapter Mount to fasten other accessories such as the Osmo Action Curved Adhesive Base Kit and the Osmo 1.5m Extension Rod.

Osmo Action Extreme Battery
The Osmo Action Extreme Battery boosts Osmo Action 4 performance across a wide temperature range from -20° to 45° C (4° F to 113° F). With a 1770 mAh capacity, the battery can continuously work for up to 160 minutes.* Refer to Battery Usage Notes for more detailed information on battery usage. Tested at room temperature (25°C/77°F) and 1080p/24fps (16:9), with RockSteady on, Wi-Fi off, and screen off. This data is for reference only.

Osmo Action Multifunctional Battery Case
The Osmo Action Multifunctional Battery Case (hereinafter referred to as the battery case) is designed for storing two microSD cards and three Osmo Action Extreme Batteries safely. Users can check the battery levels by pressing the button once or opening the battery case. The status LEDs will display the battery level. When a charger is connected to the battery case with batteries inserted, the battery case will charge the batteries. When the batteries are inserted into the battery case, with external devices connected to the USB-C port, the batteries can be used as a power bank to charge the connected external devices. The batteries with the highest power level will be charged first, followed by the remaining batteries to be charged in sequence. The batteries with the lowest power level will be discharged first, followed by the remaining batteries to be discharged in sequence. When using the battery case to charge the Osmo Action Extreme Battery, it is recommended to use the DJI 30 W USB-C Charger (not included as standard) or a USB-C charger that supports Power Delivery or PPS (Programmable Power Supply). Three batteries can be fully charged in about two hours with the DJI 30 W USB-C Charger.

• DO NOT use the battery case to charge non-DJI OSMO batteries. DJI OSMO shall not be responsible for any fault or damage caused by the use of any non-DJI OSMO battery.
• Place the battery case on a flat and stable surface when in use. Make sure the device is properly insulated to prevent fire hazards.
• DO NOT attempt to touch the metal terminals on the battery ports.
• Clean the metal terminals with a clean, dry cloth if there is any noticeable buildup.
• The battery case is not waterproof. DO NOT place it in water or spill any liquid on the case.

1. Make sure the battery and battery compartment are dry and clean before inserting the battery. Otherwise, it may affect the battery contact and waterproofing ability. Make sure the battery compartment cover is firmly fastened after the battery is inserted. Note: if the cover is properly mounted, the red marks on the bottom will not be visible.
2. Make sure the USB-C port cover is clean and closed before using. Otherwise, it will affect the device waterproofing ability.
3. Make sure the lens protective cover is clean and closed before using. Otherwise, it will affect the device waterproofing ability. Make sure the lens protective cover and lens are dry and clean. Sharp or hard objects may damage the lens and affect the ability of the device. Make sure the lens protective cover are firmly mounted and fastened.
4. Osmo Action 4 is not waterproof unless the battery compartment cover, USB-C port cover, and lens protective cover are firmly mounted and fastened. The camera is NOT waterproof when used with Osmo Action Lens Hood.
5. Avoid jumping into water at high speed with Osmo Action 4. Otherwise, the impact may result in water seepage. Make sure the camera is waterproofed before jumping into water.
6. DO NOT use Osmo Action 4 in hot springs or extreme underwater environments. DO NOT let Osmo Action 4 to come into contact with corrosive or unknown liquids.
7. Rinse the camera with clean water after using it underwater. Allow it to dry naturally before using again. DO NOT dry the camera with hot air using a hair dryer, otherwise the microphone membrane and the built-in breathable membrane will rupture, and the camera will no longer be waterproof.

Attach the waterproof case to Osmo Action 4 when using it while diving, surfing, underwater for an extended period, or in other situations involving high water impact. Observe the following precautions when using the device with the waterproof case:

1. Make sure the rubber seal is clean and firmly attached during use.
2. Make sure the waterproof case is dry (for best results, place anti-fog fiber in the case during use) and the latch is secure.

1. Before use, close the battery compartment cover and the USB-C port cover, and tighten the Lens Protective Cover. It is recommended to install the Waterproof Case for long-duration underwater shooting or in environments with high water impact pressure. Osmo Action 4 and its Waterproof Case have an IP68 waterproof rating. Do not use the camera in hot springs or extreme underwater environments, or let it come into contact with corrosive or unknown liquids.
2. EIS is not supported in Slow Motion and Timelapse modes. HorizonSteady is only available when the video resolution is 1080p (16:9) or 2.7K (16:9) with a frame rate of 60fps or below. HorizonBalancing is only available when the video resolution is 1080p (16:9), 2.7K (16:9), or 4K (16:9) with a frame rate of 60 fps or below.
3. Tested at room temperature (25°C/77°F) and 1080p/24fps (16:9), with RockSteady on, Wi-Fi off, and screen off. This data is for reference only.
