Key Specifications of the DJI Osmo Action 4

The 1/1.3-Inch Sensor – Bigger Pixels, Better Image Quality

The DJI Osmo Action 4 features a 1/1.3-inch CMOS sensor, which is significantly larger than the 1/1.7-inch sensor in the Osmo Action 3. In action cameras, sensor size directly affects image quality.

Sensor size comparison in action cameras:

What the larger sensor means for the DJI Osmo Action 4:

• Better low-light performance – Larger pixels gather more light. Nighttime, sunset, and indoor footage is cleaner with less noise.

• Improved dynamic range – Highlights and shadows retain more detail. The DJI Osmo Action 4 handles high-contrast scenes better than its predecessor.

• Shallower depth of field – You can achieve slight background separation for dramatic shots.

• 10-bit D-Log M color – Professional color grading is possible with the larger sensor’s data capture.

For action camera users who shoot in challenging lighting conditions, the DJI Osmo Action 4’s 1/1.3-inch sensor is a significant advantage.

4K 120fps Video – Smooth Slow Motion

The DJI Osmo Action 4 records 4K video at up to 120 frames per second. This is one of the highest frame rates available in an action camera at 4K resolution.

Video specifications of the DJI Osmo Action 4:

What 4K 120fps means for your action footage:

When recorded at 120fps and played back at 30fps, you get 4x slow motion. This is dramatic and cinematic. For action sports – skateboarding, skiing, mountain biking, surfing – slow motion reveals details that are invisible at normal speed.

Examples of 4K 120fps on the DJI Osmo Action 4:

• Snowboarding – The snow spray behind the rider is crisp and detailed

• Skateboarding – The rotation of the board, the grip tape texture, the landing

• Mountain biking – The suspension compressing, the dirt flying

• Surfing – The wave cresting, the water droplets suspended in air

• Motocross – The roost of dirt from the rear tire

For creators who want to produce cinematic action content, the DJI Osmo Action 4’s 4K 120fps is essential.

360° HorizonSteady Stabilization – Unshakable Footage

The DJI Osmo Action 4 features 360° HorizonSteady stabilization. This is the most advanced stabilization system in any action camera.

How HorizonSteady works on the DJI Osmo Action 4:

The DJI Osmo Action 4 camera uses a high-precision gyroscope and advanced algorithms to detect and compensate for camera rotation. Unlike standard electronic stabilization that only corrects up to 45 degrees of tilt, HorizonSteady can correct for 360 degrees of rotation.

What this means for your footage:

• The horizon stays level – No matter how much the camera rotates, the footage remains horizontal

• Floppy camera mounts become usable – Chest straps, helmet mounts, and handlebar mounts all produce smoother footage

• Walking shots look like gimbal shots – The DJI Osmo Action 4 smooths out the natural bobbing of walking

• Action sports look professional – Flipping, spinning, and rotating the camera does not ruin the footage

RockSteady 3.0+ (the high-performance mode):

For creators who want the maximum stabilization with a slight crop, RockSteady 3.0+ provides even smoother footage than HorizonSteady. This mode is ideal for:

• High-intensity action sports (motocross, downhill mountain biking)

• Running and fast walking

• Unpredictable camera movement

The DJI Osmo Action 4’s stabilization is so good that many creators no longer use gimbals for action shots.

18m Waterproof – No Housing Required 

The DJI Osmo Action 4 is waterproof to 18 meters (59 feet) without any external housing. This is a significant advantage over GoPro’s HERO series, which is waterproof to 10 meters.

What 18m waterproofing allows you to do with the DJI Osmo Action 4:

Why waterproofing matters without a housing:

• Better audio – Housings muffle sound; the built-in microphones work clearly underwater

• Better touchscreen – Housings make screens difficult to use; the direct screen works perfectly

• Less bulk – No housing means the DJI Osmo Action 4 fits in your pocket

• No fogging – Housings can fog; the sealed camera does not

For water sports creators, surfers, swimmers, snorkelers, and scuba divers, the DJI Osmo Action 4’s 18m waterproofing is essential.

Dual Touchscreens – Front and Rear

The DJI Osmo Action 4 features both a rear touchscreen and a front LCD screen.

Screen specifications:

Why dual screens matter for the DJI Osmo Action 4:

• Vlogging – The front screen lets you frame yourself when the camera is facing you

• Selfies – See yourself before you press the shutter

• Group shots – Everyone can see the frame before the camera takes the photo

• Status monitoring – The front screen shows recording status, battery, and settings

The front screen on the DJI Osmo Action 4 is bright enough to see in direct sunlight – essential for outdoor vlogging. DJI Osmo Action 4

10-Bit D-Log M Color – Professional Grading

The DJI Osmo Action 4 records 10-bit D-Log M video, which is a flat color profile designed for post-production grading.

What 10-bit color means:

Standard 8-bit video records 16.7 million colors. 10-bit video records 1.07 billion colors. This is 64 times more color information.

Why 10-bit D-Log M matters on the DJI Osmo Action 4:

• No banding in gradients – Skies, sunsets, and shadows are smooth, not posterized

• Flexible color grading – Adjust white balance, saturation, and contrast without breaking the image

• Better skin tones – More color information means more natural-looking skin

• Highlight and shadow recovery – Push exposure up or down by 2-3 stops without artifacts

For creators who color grade their footage, the DJI Osmo Action 4’s 10-bit D-Log M is a professional feature not found in most action cameras.

160-Minute Battery Life – All-Day Shooting

The DJI Osmo Action 4’s battery lasts up to 160 minutes on a single charge (1080p at 30fps). In 4K mode, battery life is approximately 90 minutes.

Battery specifications:

This Adventure Combo includes three batteries:

• One battery in the camera

• Two spare batteries in the multifunctional battery case

• Total capacity: 3 x 160 minutes = 480 minutes (8 hours) of potential recording time

For creators who shoot all day – skiing, hiking, biking, events – the DJI Osmo Action 4 Adventure Combo provides enough battery life to never miss a moment.

Multifunctional Battery Case – Charge on the Go

The Adventure Combo includes DJI’s multifunctional battery case, which serves three purposes:

1. Battery storage:

The case holds two spare batteries securely, with individual battery level indicators.

2. Battery charging:

The case charges two batteries simultaneously. Plug the case into USB-C, and both batteries charge at the same time.

3. Power bank:

The case can charge other devices. The built-in battery (not the spare batteries) provides power for your phone, camera, or other USB devices.

For travel creators, the multifunctional battery case replaces a separate battery charger and power bank.

The Included Accessory Bundle – Complete Creator Kit

This DJI Osmo Action 4 Adventure Combo includes an extensive accessory bundle:
