DJI Osmo Action 4

The Osmo Action 4’s core strength lies in its 1/1.3-inch CMOS sensor, offering notable gains in low-light sensitivity and dynamic range over previous models. The camera supports up to 4K at 120fps, making it suitable for high-frame-rate capture, slow motion, and fast-paced action scenes. Its 10-bit D-Log M color profile allows for greater color grading flexibility during post-production.

DJI continues to impress with its magnetic quick-release system, enabling rapid repositioning and a secure hold for a wide variety of mounts. The dual touchscreen design (front and rear) enhances usability, particularly for vloggers and solo shooters needing live previews.

Battery performance is a highlight. In moderate conditions, the 1,770 mAh cell delivers approximately 160 minutes of continuous operation. Furthermore, the unit is waterproof up to 18 meters without a case, reinforcing its readiness for wet and rugged environments.

The Osmo Action 4 delivers superior video fidelity, with excellent detail retention and natural color reproduction. Its ultra-wide lens captures immersive perspectives ideal for action and landscape shots. RockSteady 3.0+ stabilization significantly reduces motion artifacts, producing smooth, shake-free footage—even when handheld or mounted to a moving subject.

Battery longevity positions the Action 4 as a reliable tool for on-the-go creators who may not have regular access to charging. This is particularly beneficial for travel vloggers or field reporters.

From a hardware ergonomics perspective, the magnetic mount simplifies transitions between vertical and horizontal orientations—perfect for those switching between YouTube and social formats. The UI is streamlined, offering fast access to settings and shooting modes, and the screens remain visible even in bright outdoor light.

The camera’s build quality inspires confidence. It’s compact, impact-resistant, and weather-sealed, ideal for creators who need equipment that performs under pressure.

While the Osmo Action 4 presents noticeable refinements, they are largely iterative. Users upgrading from the Action 3 may find the sensor upgrade and slight improvements in thermal control beneficial, but not groundbreaking.

Low-light capability, while improved, remains behind some competitors in this price bracket. Video captured in dim environments tends to lose sharpness and exhibits increased noise levels, which limits its utility in indoor or nighttime scenarios without auxiliary lighting.

Additionally, at its current price point, it competes with niche alternatives like the Insta360 GO 3, which, while different in form factor, may offer more creative flexibility for certain workflows.

The Osmo Action 4 retains the physical DNA of the Action 3 while enhancing key internals:

• Upgraded sensor from 1/1.7" to 1/1.3"
• 10-bit D-Log M for improved post-processing
• Enhanced thermal management for longer 4K sessions

Despite these changes, many core features—such as the body, magnetic interface, and dual screens—remain the same. 

For those using the original Osmo Action or Action 2, the jump to Action 4 brings significant performance gains. But Action 3 users may find the generational leap modest unless specific features are must-haves.

The DJI Osmo Action 4 is engineered for tech-savvy adventurers, content creators, and mobile videographers who value reliability and video quality. It’s tailored to users who demand excellent 4K video, easy configuration, and physical durability in their workflow.

This isn’t the best choice for filmmakers focused on low-light shooting or budget-conscious buyers seeking maximum features per dollar. But for creators prioritizing stability, convenience, and environmental resilience, it’s a compelling proposition.
