DJI Osmo Action 4 Essential Combo 4K/120fps Waterproof Action Camera
Capture action moments with consistent image quality, stable footage, and flexible shooting options using the DJI Osmo Action 4 Standard Combo. Built for outdoor use, it supports high-resolution recording, strong low-light performance, and extended runtime for long sessions in different environments.
1/1.3-Inch Sensor for Low-Light Imaging
The larger 1/1.3-inch sensor improves light capture in dark or high-contrast scenes. This allows clearer footage during early morning, sunset, or night activities. It reduces noise and helps maintain detail in challenging lighting conditions.
4K/120fps Ultra-High Resolution Recording
Supports 4K video at up to 120fps for smooth motion capture and slow-motion playback. Ideal for sports, travel, and fast-moving activities where detail and clarity are important.
10-bit Color and D-Log M Profile
Records a wider color range for better post-production control. The D-Log M profile helps preserve highlights and shadows, giving more flexibility for editing and color grading.
155 Degrees Ultra-Wide Field of View
Captures a broader perspective for immersive shots. Useful for action sports, landscapes, and group scenes where a wider frame is needed without repositioning the camera frequently.
RockSteady Stabilization System
Reduces shake during movement for smoother footage. Helps maintain stable video when riding, running, or recording in uneven terrain.
Magnetic Quick Release System
Allows fast switching between horizontal and vertical shooting. Supports quick mounting changes for different shooting angles without complex setup.
Long Battery Life with Extended Recording
Provides up to 160 minutes of recording time under optimized conditions. Designed for extended outdoor sessions with fewer interruptions for charging.
Pre-Recording and Highlight Features
Pre-Rec captures footage before pressing record, ensuring key moments are not missed. Highlight tagging helps mark important clips for faster editing and review.
DJI OsmoAudio Support
Connects directly to compatible DJI microphones for improved audio capture. Useful for vlogs, interviews, and livestreams with reduced setup complexity.
Waterproof and Outdoor Ready Design
Built for outdoor environments with waterproof capability when properly sealed or used with the protective case. Suitable for water-based and rugged activities.
