DJI Osmo Action 6
Two firsts arrived on the same body: a variable aperture on an action camera, and a square 1:1 sensor instead of the usual 4:3. The aperture stepping f/2.0 to f/4.0 matters most in bright conditions, where every other action camera has to throw away light with a shutter it cannot slow down or an ND filter you have to remember to bring. The square sensor matters in the edit — the camera measures the full 1:1 frame, so a widescreen crop and a vertical crop come out of one take without either being a stretched afterthought. DJI puts the imaging area at a 4:3 one-inch equivalent; worked off the standard optical-format table the named 1/1.1-inch format gives about 96 mm², still roughly triple a GoPro Hero 13's. Add 8K30, 20 m of bare waterproofing, 64 GB of internal storage and a four-hour battery rating and it is the most complete spec sheet in the category.
Sensor area against the rest of the catalogue
Derived from the standard optical-format table rather than copied off a spec sheet, because makers print a fraction that hides it. The table and the arithmetic.
Battery, with the small print
- Maker’s claim
- 4 h at 1080p24 with RockSteady on
- Third-party test
- None collected. We publish a tested figure only where a named outlet has run one and stated its conditions.
Specifications
Features
- ●Variable f/2.0–f/4.0 aperture, the first on an action camera
- ●Square 1:1 sensor that crops to 16:9 and 9:16 from one take
- ●8K30, 5.3K60, 4K120 and 1080p240
- ●10-bit colour with D-Log M
- ●Waterproof to 20 m with no housing
- ●64 GB of internal storage as well as a microSD slot
- ●Magnetic quick-release mount
- ●Rated to −20 °C
Strengths
- +Variable aperture solves the one problem no other action camera can: too much light
- +Square sensor makes vertical and landscape cuts from the same file without cropping into nothing
- +Roughly triple the sensor area of a GoPro Hero 13, which is visible the moment the sun goes down
- +20 m bare waterproofing and a −20 °C rating with no housing
- +64 GB built in, so a forgotten microSD card is not a dead day
- +Four-hour battery rating is the longest here, even allowing for the 1080p24 setting it is quoted at
Drawbacks
- −No GPS, so there is no speed or altitude overlay without a phone
- −Mounting is magnetic-only; GoPro-fingered accessories need an adapter
- −8K caps at 30 fps and the 120 Mbps ceiling is low for that resolution
- −Four hours is quoted at 1080p24 — at 8K it is a fraction of that
- −The magnetic latch is the only mount on the body; there is no 1/4-20 thread
What owners say
Summarised from owner discussions and published long-term reviews.
Two firsts arrived together here, and owners rate them in the opposite order to the press. The square 1:1 sensor is the one that changes daily work — the camera measures a square frame, so a widescreen crop and a vertical crop come out of the same take without either looking like an afterthought. The variable f/2.0–f/4.0 aperture matters most in bright conditions, on snow and water, where every other action camera has to throw away light it cannot stop down.
The reason owners keep choosing DJI over GoPro, though, is duller than either feature: heat and battery. Overheating shutdowns are the single most repeated GoPro complaint, and DJI owners report them far less; runtime is longer by a wide margin even after discounting DJI's 1080p24 headline figure. Twenty metres of bare waterproofing and 64 GB of internal storage add to that practical picture.
What owners give up is GPS and the GoPro mount ecosystem. Neither is fatal — adapters exist and most people do not overlay telemetry — but both come up in every switching thread, and the mount question in particular catches people who own a decade of GoPro-fingered clamps.
What owners like
- +The variable aperture is the feature owners did not know they wanted — it solves overexposure in snow and on water without carrying ND filters
- +The square sensor genuinely changes the edit: owners delivering both widescreen and vertical cut both from one take rather than shooting twice
- +Owners consistently report that it does not shut down from heat the way GoPros do, which is the single most common reason people switch brands
- +64 GB of internal storage has saved more than one owner whose card was in another jacket
- +Battery life is the other reason people switch, and the reports back up DJI's advantage even after discounting the 1080p24 headline
Common complaints
- −No GPS, so there is no speed or altitude overlay without carrying a phone or a watch
- −Magnetic-only mounting means an adapter for anything GoPro-fingered, and owners with a decade of GoPro mounts find that irritating
- −The 120 Mbps ceiling is low for an 8K mode, and owners shooting detailed scenes at 8K notice the compression
- −DJI's app and desktop tools get less praise than the hardware, particularly for organising footage
Questions owners keep asking

Now that the Action 6 has taken the flagship slot, this is the value argument in the whole category: a 1/1.3-inch sensor with more than twice the area of a GoPro Hero 13's, 20 m of bare waterproofing, 47 GB of internal storage and a genuinely long-running battery, for around three hundred dollars. It gives up the Action 6's variable aperture and square readout and caps at 4K rather than 8K — which matters less than the spec gap suggests, because 4K120 covers almost everything an action camera is actually used for. In an independent four-camera drain test it ran 2 hours 14 minutes, well behind DJI's 1080p24 headline of four hours but comfortably ahead of the Insta360 Ace Pro 2.
The camera that made a large sensor normal at this price, and it is still on sale two generations later because the fundamentals have not aged. Same 1/1.3-inch chip as the Action 5 Pro, same 4K120, same 10-bit D-Log M, same magnetic mount, 18 m waterproof against the newer model's 20. Where it falls short is the stills sensor readout — 10 MP against 40 — the smaller rear screen, and the absence of internal storage. The 130 Mbps ceiling is actually a touch higher than the Action 5 Pro's. At a street price around $229 it is the cheapest way to get a sensor this size into a waterproof body, and for anyone who mostly shoots video rather than photos the compromises are close to invisible.

DJI Osmo 360
DJI's first 360 camera arrived with the two square 1:1 sensors from the Action 6 programme, which is the most interesting thing about it: a square sensor wastes less of the lens's circular image than a 4:3 one, so more of the light the fisheye collects ends up in the sphere. The result is 8K at 50 fps — the only 360 camera here that gets past 30 at 8K — 170 Mbps, 10-bit across every format, D-Log M, 120 MP panoramas, and a single-lens mode that runs 4K120 with a 155° field of view. It is also the only 360 camera in the catalogue with more than 100 GB of internal storage, which removes the write-speed argument that sinks so many 360 shoots. Against the Insta360 X6 it gives away half the bare waterproof depth, and DJI's reframing app is younger than Insta360's.
