underwater performance has become one of the most important factors in choosing an action camera. DJI has answered
that demand with significant upgrades.

The DJI Action 6 at a Glance
According to the official DJI Action 6 specifications, the camera includes:
- 1/1.1-inch square CMOS sensor
- Variable mechanical aperture f/2.0–f/4.0
- Waterproof to 20 m without a housing
- Up to 4 hours battery life (lab conditions)
- 50 GB internal storage
- 4K/120fps in a 4:3 recording format
- HorizonSteady stabilisation
These core improvements form the base of its underwater capability.
Underwater Performance: What’s New and Why It Matters
20 m Waterproofing Without a Housing
DJI lists the Action 6 as waterproof to 20 m with no case needed.
This information is confirmed on the official DJI support page
The depth rating covers:
- Snorkelling
- Reef filming
- Drift or trolling setups
- Shallow dives
- Seabed viewing from fixed rigs
For deeper conditions, DJI offers a dedicated waterproof case also found in the Action 6 accessory section of the official DJI store
Improved Low Light Performance from the New 1/1.1-Inch Sensor
Underwater, light falls off quickly. DJI’s 1/1.1-inch square sensor captures more light and detail
and is one of the largest sensors available in an action camera today.

The benefits underwater include:
- Cleaner footage in deeper water
- Better clarity in murky or moving water
- Improved detail in shadows
- More realistic colours without heavy correction
Variable Mechanical Aperture (f/2.0–f/4.0)
This is one of the Action 6’s standout features and is highlighted on DJI’s spec sheet
A mechanical aperture gives genuine control underwater:
- f/2.0 boosts brightness in deep or low-visibility conditions
- f/4.0 protects highlights in shallow, bright water
- More accurate exposure across changing underwater scenes
This level of exposure control is rare in action cameras and a significant advantage underwater.
4K/120fps + 4:3 Sensor for Flexible Underwater Composition
The Action 6 captures 4K/120fps in 4:3, which allows more vertical composition, extremely useful
underwater where subjects often move up and down as much as left and right.
The recording modes are detailed on the Action 6 tech specs page
Advanced Stabilisation That Works Underwater
DJI’s HorizonSteady stabilisation and updated RockSteady algorithms help manage the unpredictable
movement that happens underwater. From drifting current to small surges, stabilisation ensures smoother, clearer
footage that remains usable even without extra rigging.

Why These Upgrades Matter for Underwater Users
These advancements translate into meaningful benefits:
- Clearer footage at greater depths
- More natural colours without filters
- Stronger low-light performance
- Improved stability while drifting or filming moving subjects
- Greater reliability thanks to strong native waterproofing
Anyone capturing underwater content, from fishing to filmmaking, will notice the improvement immediately.
Final Thoughts
The DJI Action 6 delivers significant real-world upgrades for underwater filming. With a large sensor, variable
aperture, improved stabilisation and strong native waterproofing, it sets a new standard for compact
underwater-friendly action cameras.
