DJI Osmo Action 4 vs DJI Osmo Action 5 Pro

1. Sensor & Image Quality

• Both cameras feature a 1/1.3-inch sensor, but the Action 5 Pro’s sensor uses more advanced technology—it can capture up to 40 MP photos, whereas the Action 4 is limited to 10 MP.

• The Action 5 Pro has a dynamic range of ~13.5 stops, which helps maintain balance between highlights and shadows.

2. Battery Life

• The Action 4’s battery lasts around 160 minutes, but thanks to a 4nm chip and a new battery, the Action 5 Pro can run for up to 240 minutes.

• According to The Verge, lab tests showed up to 4 hours of recording at 1080p/24fps. In real-world use, runtime may vary depending on capture settings and environment.

3. Display & User Interface

• The Action 4 had LCD screens (front and back), whereas the Action 5 Pro introduces OLED screens—brighter, larger, and more colorful.

• During post-production, visibility and color accuracy are much better on OLED.

4. Stabilization (Trial by Fire)

• The Action 4 featured RockSteady stabilization, while the Action 5 Pro adds more advanced options such as RockSteady+, HorizonSteady, and HorizonBalancing.

5. Internal Storage

• The Action 4 came with no built-in storage, requiring a microSD card.

• In contrast, the Action 5 Pro includes 47 GB of fast internal storage, making it more convenient right out of the box.

6. Waterproofing & Environmental Resistance

• The Action 4 is waterproof down to 18 meters (without a case).

• The Action 5 Pro extends this to 20 meters (without a case), plus it includes a pressure gauge and better environmental resistance.

7. New Features
The Action 5 Pro adds several features not found in the Action 4:

• SuperNight — AI-powered night mode for improved low-light photos/videos.

• Subject Tracking — keeps a subject in focus and centered in the frame.

• DJI Mic 2 (Bluetooth) support — for improved audio recording.

• Wi-Fi 6 and USB 3.0 connectivity — faster and smoother transfers.

8. User Opinions (from Reddit)

• Bitrate — The Action 4’s video bitrate is about 30% higher, reducing compression and preserving better video quality.

• General use in open air — The Action 5 Pro’s internal storage, battery life, and OLED screen are valuable improvements, but image quality differences aren’t drastic.
