DJI Osmo Action 5 Pro
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.
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
- 2 h 14 min — continuous recording to shutdown, four cameras run simultaneously at one matched resolution (resolution not published). Published by road.cc action camera group test.
Specifications
Features
- ●1/1.3-inch sensor, over double a Hero 13's imaging area
- ●4K120 and 1080p240 slow motion
- ●10-bit colour with D-Log M
- ●Waterproof to 20 m with no housing
- ●47 GB of usable internal storage
- ●2.5-inch rear OLED plus a front screen
- ●Rated to −20 °C
Strengths
- +Double the sensor area of a Hero 13 for less money than one
- +Beat the Ace Pro 2 by half an hour in a same-conditions drain test
- +Internal storage means the camera still records when the card is in the other jacket
- +Twice the bare waterproof depth of any GoPro Hero
- +Rear OLED is the best screen on any action camera at this price
Drawbacks
- −Tops out at 4K — no 5.3K or 8K mode
- −No GPS overlays
- −Magnetic-only mount needs an adapter for GoPro-fingered accessories
- −Real-world runtime is closer to two hours than the four DJI quotes at 1080p24
- −Fixed f/2.8 aperture, so bright snow and water still need an ND filter the Action 6 does not
What owners say
Summarised from owner discussions and published long-term reviews.
This is the camera the discussion recommends most often to someone who wants better footage without paying flagship money, and the reason is the sensor. At roughly double a GoPro Hero's imaging area it is visibly better in the conditions where action cameras usually fall apart — dusk, shade, indoors — and owners who have both describe the difference as obvious rather than marginal.
The practical specs back it up. Twenty metres of bare waterproofing, 47 GB of internal storage, and battery life that beat the Insta360 Ace Pro 2 by half an hour in a test where four cameras ran simultaneously to shutdown. Owners rarely complain about running out of power on this camera.
What holds it back is resolution and the arrival of its successor. Four thousand pixels wide is the ceiling, and if you crop or reframe heavily you will want more. And the Action 6 adds two features this camera cannot gain in firmware. At its current discounted price, though, owners treat it as the value pick of the whole category.
What owners like
- +Owners describe this as the camera that made the sensor gap to GoPro obvious, and it is the most common recommendation for anyone shooting in poor light
- +Real-world runtime comes out ahead of the equivalent GoPro in independent testing, and owners report the same in the field
- +47 GB of internal storage removes the forgotten-card failure entirely
- +Twenty metres bare is twice any GoPro Hero, and owners who snorkel and dive take it without a housing
- +The rear OLED is the best screen on any action camera near the price and stays readable in sun
Common complaints
- −Now that the Action 6 exists, owners note this one is missing both the variable aperture and the square sensor
- −Caps at 4K — there is no 5.3K or 8K, which matters if you crop heavily in the edit
- −No GPS
- −Magnetic-only mount needs an adapter for GoPro-fingered accessories

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.

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.

Fifty-two grams, and a 1/1.3-inch sensor inside them — the same size chip DJI puts in a full-size Osmo Action. That is the trick here, and it is why the Nano reads differently from every other tiny camera in the category, all of which shrink the sensor along with the body. It splits in two: the camera module clips onto a magnet under a shirt or on a helmet, and the Vision Dock adds an OLED screen, a second battery and a microSD slot when you want to frame a shot or run long. Alone the module is waterproof to 10 m and lasts about 90 minutes; docked, DJI rates the pair at 200 at 1080p24. What it does not have is full horizon lock — HorizonBalancing corrects tilt, not rotation — and the magnetic pendant is a trust exercise at speed.
