Quick Answer: The DJI Osmo Action 6 is DJI’s new flagship action camera, launched in November 2025 at $379 for the Standard Combo ($479 Adventure Combo), and it’s the first action camera with a variable aperture (f/2.0-f/4.0) alongside a larger 1/1.1-inch sensor and 8K video up to 30fps. The variable aperture sounds like a depth-of-field tool, but per outlets like Digital Camera World that tested it, its real value is light control — stopping down in bright sun or opening up indoors — since action-cam optics keep almost everything in focus regardless of aperture. It’s 20m waterproof without a case and rated for 240 minutes per 1950mAh battery, the same headline numbers as the Action 5 Pro it replaces as DJI’s top tier.
DJI’s Osmo Action line has iterated on the same formula for years: bigger sensor, better stabilization, deeper waterproofing. The Action 6 is the first entry that adds genuinely new hardware — a mechanically adjustable aperture — rather than just refining the same fixed-aperture formula. This review covers what that aperture actually does in practice, what else changed, and whether it’s worth $60 more than the Action 5 Pro DJI was selling as its flagship just months earlier.
What the DJI Osmo Action 6 actually is
Announced globally in November 2025, the Osmo Action 6 is built around a 1/1.1-inch CMOS sensor — DJI’s largest yet in an action camera, up from the Action 5 Pro’s 1/1.3-inch — paired with a 155° FOV lens and, for the first time on any action camera, a variable f/2.0-f/4.0 aperture you adjust from the app or the camera’s own touchscreens. DJI rates dynamic range at 13.5 stops and peak photo resolution at roughly 38MP (7168x5376).

The body carries two color touchscreens — a 1.46-inch front display and a 2.5-inch rear display — weighs 149g, and ships with 64GB of built-in storage (50GB usable) plus microSD expansion. It’s rated for 20m of waterproofing with no case required, matching the Action 5 Pro’s depth rating rather than improving on it.

The variable aperture, honestly
This is the feature DJI is marketing hardest, and it’s genuine new hardware — no other action camera on the market lets you dial in an aperture between f/2.0 and f/4.0. But it’s worth being precise about what that buys you. Digital Camera World’s review, titled bluntly around whether the Action 6 is “a tiny real camera,” found that a smaller aperture’s classic photographic benefit — a deeper depth of field that keeps more of a scene in focus — barely matters here: action-camera sensors are small and paired with genuinely wide lenses, so beyond about 35cm from the lens, everything is already in focus at any aperture setting. The marketing angle of cinematic selective focus doesn’t really apply.
What the variable aperture is actually good for is exposure control. Stopping down to f/4.0 on a bright, snowy slope or sunlit beach cuts down blown highlights without reaching for a separate ND filter kit; opening up to f/2.0 indoors or at dusk lets in more light than a fixed f/2.8 lens can. That’s a real, practical upgrade for anyone who’s fought overexposed footage on a sunny day with a fixed-aperture action cam — just don’t expect it to make your GoPro-style clips look like they were shot on a mirrorless camera.
Where it beats — and doesn’t beat — the Action 5 Pro
| Spec | Osmo Action 6 | Osmo Action 5 Pro |
|---|---|---|
| Sensor | 1/1.1-inch | 1/1.3-inch |
| Aperture | Variable f/2.0-f/4.0 | Fixed f/2.8 |
| Max video | 8K/30fps | 4K/120fps |
| Waterproof (caseless) | 20m | 20m |
| Battery (rated) | ~240 min | ~240 min |
| Weight | 149g | 146g |
| Price (Standard) | $379 | ~$319 |
The two generations tie on waterproofing, rated battery life, and weight — the Action 6’s real gains are the bigger sensor, the variable aperture, and 8K capture for footage you plan to crop or reframe heavily in post. If you mostly export 4K for YouTube or social and don’t need to punch in during editing, the Osmo Action 5 Pro still delivers essentially the same everyday footage for $60 less.
By the numbers
- f/2.0-f/4.0: the Osmo Action 6’s adjustable aperture range — DJI’s first on any action camera, per its own spec sheet.
- 13.5 stops: DJI’s rated dynamic range, matching the Action 5 Pro’s figure despite the larger sensor.
- $60: the price gap between the Action 6’s $379 Standard Combo and the Action 5 Pro’s ~$319 Standard Combo.
- 35cm: roughly the distance beyond which action-camera optics keep everything in focus regardless of aperture setting, per Digital Camera World’s testing — the practical ceiling on the variable aperture’s depth-of-field benefit.
- 20m: caseless waterproof depth, unchanged from the Action 5 Pro.
The bottom line
The DJI Osmo Action 6 is a genuine hardware step forward — the bigger 1/1.1-inch sensor, 8K capture, and especially the variable aperture are real upgrades, not a repackaged Action 5 Pro. Just go in with the right expectations for that aperture: it’s a light-control tool for tricky exposure, not a shortcut to shallow-depth-of-field cinematic footage. If you shoot in consistently harsh sun or want maximum cropping headroom from 8K, the $60 premium over the Osmo Action 5 Pro is worth it. If you just want DJI’s reliable 4K action-cam experience, the 5 Pro still delivers nearly identical everyday footage for less.
