These three cameras get compared constantly, and they shouldn't be — not like this. The Insta360 Luna Ultra is a $769.99 gimbal vlogging camera (checked 28 September 2026) with a mechanical 3-axis gimbal, two lenses and no water, dust or splash resistance whatsoever. The GoPro HERO13 Black ($429.99, checked 28 September 2026) and DJI Osmo Action 5 Pro ($319.00 at B&H, same date) are waterproof action cameras, rated to 10m and 20m bare respectively, built to be bolted to a helmet and dropped. Putting all three in a table and declaring one "best" produces an answer that is wrong for everybody, because the three cameras do not do the same job.
That matters commercially as well as editorially. If you read a ranking that puts the Luna Ultra first on image quality, buy it, and then take it out in the rain — which is a normal thing to do with a camera you were told beat two waterproof action cameras — you have a $769.99 problem and no warranty argument. So this page does three things instead of ranking them: it lays out what each camera actually is, it answers the real question ("which of these should I buy?") by use case rather than by score, and it points you at the comparison that is genuinely like-for-like. If you want a pocket gimbal camera, your real shortlist is Luna Ultra vs DJI Osmo Pocket 3. If you want an action camera, your real shortlist is Insta360 Ace Pro 2 vs Osmo Action 5 Pro vs HERO13 Black. Both of those are proper fights; this one isn't.
Specs at a Glance
Every row the original table carried is retained. Two rows have been added: Type and Weather sealing. Those two rows are the whole story.
| Feature | Insta360 Luna Ultra | GoPro HERO13 Black | DJI Osmo Action 5 Pro |

Swipe for 1 more column →
⚠️ The two rows that matter most. The Luna Ultra has no water, dust or splash rating — not "limited", not "5m", not "splash-resistant". Insta360 publishes none, which means there isn't one. And at 233g it is 74g heavier than the HERO13 and 87g heavier than the Action 5 Pro, on a device with a moving mechanical gimbal head that is the most fragile part of any camera on this page.
⚠️ HERO13 weight: B&H lists 121g, which is almost certainly body-only. Digital Camera World's spec table gives 159g with battery, and that is the figure used here. Do not confuse it with the HERO12 Black at 154g.
Also worth stating: the HERO13 Black is no longer GoPro's flagship camera. There is no HERO14 Black. GoPro launched the MISSION 1 series instead, priced 20 April 2026 at $599.99 / $699.99. The HERO13 remains the current HERO-line flagship and is still sold at $429.99 (checked 28 September 2026) — $170 less than the MISSION 1, so it is the cheaper GoPro rather than a halo product, though it now costs $60 more than Insta360's current flagship, the Ace Pro 2.
Insta360 Luna Ultra — What It Actually Is
Insta360 Luna Ultra — $769.99, checked 28 September 2026
Verdict: Excellent for controlled-environment vlogging; unsuitable for anything an action camera is for
The Luna Ultra is a gimbal vlogging camera, and the single most useful thing on its spec sheet has nothing to do with the two cameras it's being compared with: it has two lenses. A 20mm-equivalent wide at F1.8 on a 1-inch sensor, and a 60mm-equivalent optical telephoto at F2.0 on a 1/1.3-inch sensor, with a 1×–12× zoom range across them. That is a real focal-length change, not a crop. Neither the HERO13 Black nor the Action 5 Pro has any optical zoom at all.
The rest of the hardware is built for the same job. A 3-axis mechanical gimbal accurate to ±0.005° — physical stabilisation, not electronic, so it costs you no crop and no resolution. 240 minutes of rated runtime from a 1550mAh cell, with 23 minutes to 80% off a 45W charger. A 2.0-inch OLED at 1000 nits, the brightest screen of these three, which is the difference between framing yourself in direct sun and guessing. 47GB of internal storage so a forgotten card doesn't end the shoot. And 8K capture, per Insta360's own marketing.
Then the wall. The Luna Ultra has no water, dust or splash resistance. No depth rating, no IP code, nothing published. It is 233g, the heaviest camera here, with an exposed mechanical gimbal head. It has no mounting fingers and no waterproof housing in the range. It costs $769.99 — $340 more than the HERO13 Black and $450.99 more than the Action 5 Pro. Insta360's own dive-capable and mountable cameras are different products entirely; this one is not in that category and was never meant to be.
＋ Pros
- Two lenses — 20mm wide plus a real 60mm optical telephoto
- 1-inch main sensor at F1.8, the widest aperture on this page
- 1×–12× zoom range
- 3-axis mechanical gimbal, ±0.005° — no stabilisation crop
- 240 min rated runtime, level with the DJI and the longest here
- 23 min to 80% fast charge (45W); neither rival publishes a figure
- 1000-nit OLED screen, brightest of the three
- 47GB internal storage
- 8K capture (Insta360 marketing figure)
− Cons
- No water, dust or splash resistance of any kind ⚠️ — the single most important line on this page
- $769.99 — $340 more than the HERO13, $450.99 more than the Action 5 Pro
- 233g, the heaviest here, with an exposed mechanical gimbal head
- No mounting fingers, no housing — you cannot helmet-, chest- or bar-mount it like an action camera
- Insta360 publishes no photo resolution figure for it
- The Insta360 App cannot export 8K on mobile — that needs Insta360 Studio on a desktop
- Not the right camera for any use case the other two on this page are built for
GoPro HERO13 Black — What It Actually Is
GoPro HERO13 Black — $429.99 at GoPro, checked 28 September 2026
Verdict: The stabilisation benchmark for mounted POV, now the cheaper GoPro rather than the flagship
The HERO13 Black is an action camera: waterproof to 10m with no housing, 159g, and fitted with GoPro's folding-finger mount standard, which every helmet mount, chest harness, bar clamp and suction cup on earth is designed around. It shoots 5.3K60, 4K120 and 2.7K240 off a 1/1.9-inch 27.6MP sensor, and it is the one camera on this page with a published stabilisation version number: HyperSmooth 6.0.
That version number matters more than it sounds. GoPro does not publish a HyperSmooth version for its new MISSION 1 flagship. On the HERO13 it does, and HyperSmooth 6.0 remains the reference point for chest- and helmet-mounted walking, running and riding footage. If most of what you shoot is a camera strapped to a moving body, this is the machine for it and the Luna Ultra is not a candidate at any price.
Its weaknesses against the DJI are straightforward. The 1/1.9-inch sensor is the smallest here — a full size class below the Action 5 Pro's 1/1.3-inch — and you see it once the light drops. 10m bare waterproofing is half the DJI's 20m. GoPro's only published runtime for the 1900mAh Enduro cell is >1.5 hours at 5.3K30; it publishes no fast-charge figure and no dynamic-range figure, and there is no built-in storage. And at $429.99 it is $110.99 more than the DJI.
＋ Pros
- HyperSmooth 6.0 — the one published stabilisation version on this page
- 5.3K60 plus 4K120 and 2.7K240
- Waterproof to 10m bare
- 159g — lighter than the Luna Ultra by 74g
- Deepest mount and accessory catalogue of any brand
- First-party ND Filter 4-Pack HB-Series at $49.99, plus Freewell, PolarPro and K&F Concept options
- $429.99 is $170 less than GoPro's MISSION 1 flagship
− Cons
- 1/1.9-inch sensor — the smallest of the three
- 10m bare waterproofing, half the DJI's
- Only a >1.5 h (5.3K30) runtime published; no fast-charge or dynamic-range figure
- No built-in storage
- $110.99 more than the DJI Osmo Action 5 Pro
- No longer GoPro's flagship — the MISSION 1 series is
DJI Osmo Action 5 Pro — What It Actually Is
DJI Osmo Action 5 Pro — $319.00 at B&H, checked 28 September 2026 (DJI's US store lists it at $319 but it is out of stock in every combo)
Verdict: The best action camera on this page on hardware and price, and the only one you should take diving
The Action 5 Pro is the cheapest camera on this page at $319.00 and, measured against the other action camera here, the better one. A 1/1.3-inch sensor a full size class above the HERO13's 1/1.9-inch. 240 minutes of rated runtime from a 1950mAh cell. 20m bare waterproofing and 60m cased, which covers most recreational diving. 146g, the lightest body here. 64GB of built-in storage (47GB usable), which saves shoots when a card fails or stays at home. RockSteady 3.0 / 3.0+ with HorizonSteady, which holds a level horizon through full camera rotation. Screens front and rear, 2.5-inch and 1.46-inch.
Against the Luna Ultra it wins everything that involves weather, water, mounting or money, and loses everything that involves lenses and zoom — because it has one lens, no optical zoom, and no gimbal.
Its limits: 4K120 is the ceiling, so there is no 5K or 8K crop room. f/2.8 is the narrowest aperture here. DJI's spec table carries no dynamic-range figure, and DJI publishes no fast-charge figure. And it is a generation behind: the current DJI flagship is the Osmo Action 6 at $436.00 at B&H (checked 28 September 2026; DJI publishes no USD price), with a larger 1/1.1-inch square sensor and a variable f/2–f/4 aperture — though DJI does not officially sell the Action 6 in the USA.
＋ Pros
- $319.00 — cheapest camera on this page: $110.99 under the HERO13 Black, $50.99 under the Ace Pro 2
- 20m bare waterproofing, 60m cased — the only camera here for diving
- 240 min rated runtime
- 1/1.3-inch sensor, a size class above the HERO13's
- 146g — lightest here
- 64GB built-in storage (47GB usable)
- RockSteady 3.0 / 3.0+ with HorizonSteady
- Front and rear screens
− Cons
- 4K120 ceiling — no 5.3K, no 8K
- f/2.8, the narrowest aperture here
- No dynamic-range figure in DJI's spec table, and no published fast-charge figure
- No optical zoom, one lens
- Superseded by the Osmo Action 6 ($436.00 at B&H, checked 28 September 2026), which has a larger sensor and a variable aperture
The Category Error, Stated Plainly
Here is the comparison the original version of this page made, reduced to its two decisive rows:
| Insta360 Luna Ultra | GoPro HERO13 Black | DJI Osmo Action 5 Pro | |
|---|---|---|---|
| Type | Gimbal vlogging camera | Action camera | Action camera |
| Water / dust / splash | NONE | 10m bare | 20m bare, 60m cased |
Swipe for 1 more column →
Once those rows are on the page, "which of these three is best?" stops being answerable. A camera with no weather sealing cannot win a comparison against two waterproof cameras any more than a studio microphone can win a comparison against two helmets. The categories don't overlap, so the ranking has no meaning — and worse, publishing one implies the Luna Ultra can do things it cannot.
That implication is the actual harm. Every criterion the original ranked — stabilisation, video quality, low light, battery life — is a criterion you can only exercise once you've got the camera to the location. Rain on a hiking trail, spray from a lake, snow, a dropped camera on gravel, a sweaty chest mount: those are ordinary conditions for an action camera and terminal conditions for the Luna Ultra. Its 233g and its exposed mechanical gimbal head make the drop risk worse, not better. And at $769.99 it is the most expensive thing you could pick to find that out with.
None of which is a criticism of the Luna Ultra as a product. It is an excellent gimbal camera. Two lenses with a real 60mm optical telephoto, F1.8 on a 1-inch sensor, 240 minutes of runtime, a 1000-nit screen, 47GB of internal storage — that is a strong specification, and there is a reader for whom it is exactly right. That reader is not shopping for an action camera. So let's split them.
Which of These Should You Buy? Segment by Use Case
No scores, because scores across categories are the problem. Find your row instead.
| What you actually shoot | Buy | Why, in specifications |
|---|---|---|
| Talking to camera, indoors, cafés, streets, controlled conditions | Insta360 Luna Ultra | 1000-nit screen to frame yourself, F1.8 on a 1-inch sensor, mechanical gimbal with no crop, 240 min runtime, 47GB internal |
| Subjects at a distance — kids' sport, wildlife, stage, street from across the road | Insta360 Luna Ultra | A real 60mm optical telephoto and 1×–12× zoom. Neither rival has any optical zoom |
| Diving, snorkelling, surfing, anything submerged | DJI Osmo Action 5 Pro | 20m bare, 60m cased. The Luna Ultra has no water resistance and the HERO13 stops at 10m |
| Rain, snow, mud, cold, or any chance of a drop | DJI Osmo Action 5 Pro or GoPro HERO13 Black | Both are sealed and mountable. The Luna Ultra is neither |
| Chest- or helmet-mounted POV — running, riding, skiing | GoPro HERO13 Black | HyperSmooth 6.0, the only published stabilisation version here, plus the deepest mount catalogue |
| All-day shooting without a charger | DJI Osmo Action 5 Pro or Insta360 Luna Ultra | Both rated at 240 min. GoPro's only published figure is >1.5 h at 5.3K30 |
| Tightest budget | DJI Osmo Action 5 Pro — $319.00 | $110.99 under the GoPro, $450.99 under the Luna Ultra |
| Highest resolution | Insta360 Luna Ultra (8K) — but see below | If you want 8K and waterproofing and mounting, neither camera on this page delivers it. The Insta360 Ace Pro 2 does, at $369.99 |
That last row is the one most readers land on, so it gets its own answer in the next two sections.
If You Want a Gimbal Camera: The Right Comparison
The Luna Ultra's real rival is not an action camera. It is the DJI Osmo Pocket 3 at $439.00 (B&H, checked 28 September 2026; DJI's US store lists it at $439 but it is out of stock) — the other pocket gimbal camera you can actually buy in the United States. That comparison is close, decidable, and worth your time in a way this page's original framing wasn't.
The headline differences: the Luna Ultra has two lenses against the Pocket 3's one, including a 60mm optical telephoto where the Pocket 3 offers digital-only 2× zoom at 4K. F1.8 against f/2.0. 240 minutes against 166. 1000 nits against 700. 47GB internal against none — the Pocket 3 takes microSD only. 8K against 4K120. The Pocket 3 wins on weight (179g vs 233g) and wins comfortably on price ($439.00 vs $769.99, a $330.99 gap). Neither is water-rated: the Pocket 3 is "not rated" and the Luna Ultra has no rating at all.
And there is one fact that changes this comparison for a US buyer specifically. DJI's dual-lens answer to the Luna Ultra exists — the Osmo Pocket 4P, with a 1-inch wide plus a 1/1.28-inch telephoto — and it is not officially sold in the United States. Neither is the single-lens Osmo Pocket 4. No DJI US listing, no B&H listing; grey-market importers only. PetaPixel, 16 April 2026: "The DJI Osmo Pocket 4 isn't available in the US and it might never be." PetaPixel, 30 July 2026, on the 4P: "available everywhere except the USA." Digital Camera World, 31 July 2026: "no authorized US retailer currently has official DJI Osmo Pocket 4P stock — and DJI has not announced a formal US launch."
So if you are buying in the US and you want a dual-lens pocket gimbal with a proper optical telephoto, the Luna Ultra is not the better of two options. It is the only option you can buy with a US warranty and US support. That is a considerably stronger argument for it than anything in the original three-way ranking.

If You Want an Action Camera: The Right Comparison
If what you actually want is a camera you can mount, submerge, drop and shoot 8K on, the Luna Ultra is not in the conversation and neither of the other two cameras on this page will give you all four. The cheapest non-360 action camera that does is the Insta360 Ace Pro 2 at $369.99 (checked 28 September 2026) — $60 less than the HERO13 Black, though $50.99 more than the Action 5 Pro.
Against the two on this page: 8K30 against the HERO13's 5.3K60 and the DJI's 4K120. A 1/1.3-inch sensor, matching the DJI's and a size class above the HERO13's, behind an F2.6 Leica SUMMARIT lens. 13.5 stops of stated dynamic range, where neither the HERO13 Black nor the Action 5 Pro has a published figure. 50MP stills against the HERO13's 27.6MP and no published DJI figure. 12m bare waterproofing, better than the HERO13's 10m. A 2.5-inch flip screen at 900 nits, the only articulating screen of the three action cameras compared here. 18 minutes to 80% off a 30W charger. PureVideo low-light mode. And a published operating range of −20°C to 45°C — the same range DJI publishes for the Osmo Action 5 Pro (checked 28 September 2026), and one GoPro does not state for the HERO13 Black.
Its losses against these two, stated straight: 180 minutes of runtime against the DJI's 240. 12m against the DJI's 20m, so for diving the DJI is still the right answer. 184g against 159g and 146g — the Ace Pro 2 is the heaviest of the three action cameras, though still 49g lighter than the Luna Ultra. And note that the current GoPro flagship, the MISSION 1 at $599.99 (checked 28 September 2026), has a 1"-type 50MP sensor that is larger than the Ace Pro 2's — and the MISSION 1 PRO above it, at $699.99, shoots 8K60 against the Ace Pro 2's 8K30. Both MISSION 1 models also publish 14 stops of dynamic range, beating the Ace Pro 2's 13.5; of Insta360's cameras, only the X6, at 14.5 stops, publishes more. The MISSION 1 costs $230 more than the Ace Pro 2; the PRO, $330 more.

Signed verdictWilliam Madden · 2026-09-28
The honest verdict
There is no winner, because there is no contest. One of these three cameras has no weather sealing and cannot be mounted; the other two are waterproof and mountable and cannot zoom.
- Buy the Insta360 Luna Ultra ($769.99) if you vlog in controlled conditions or shoot subjects at a distance — and in the US it is the only dual-lens pocket gimbal you can legitimately buy, because DJI's Osmo Pocket 4 and 4P are not officially sold there.
- Buy the DJI Osmo Action 5 Pro ($319.00) if you want an action camera and value hardware over resolution. Cheapest here, 20m bare, 240 minutes, 64GB built in.
- Buy the GoPro HERO13 Black ($429.99) if you live on a chest or helmet mount. HyperSmooth 6.0 is still the reference.
- Buy neither of the action cameras above, and not the Luna Ultra either, if you want 8K plus waterproofing plus mounting in one body. That is the Insta360 Ace Pro 2 at $369.99 — $60 less than the HERO13 Black, though $50.99 more than the Action 5 Pro.
Then go and read the comparison that fits: Luna Ultra vs Osmo Pocket 3 for gimbal cameras, GoPro vs DJI vs Insta360 for action cameras.
Frequently asked questions
Which of these three cameras should I buy?
It depends on which category you're actually shopping in, and the three cameras aren't in the same one. For controlled-environment vlogging and any subject at a distance, the Insta360 Luna Ultra ($769.99) — it has two lenses including a real 60mm optical telephoto, F1.8 on a 1-inch sensor, 240 minutes of runtime and a 1000-nit screen. For anything wet, mounted or droppable, the DJI Osmo Action 5 Pro ($319.00) — 20m bare waterproofing, 240 minutes, 64GB built in, and the cheapest of the three. For chest- and helmet-mounted POV specifically, the GoPro HERO13 Black ($429.99) and HyperSmooth 6.0. If you want 8K and waterproofing and mounting, none of these three is the answer — the Insta360 Ace Pro 2 at $369.99 (checked 28 September 2026) is.
Is the Insta360 Luna Ultra waterproof?
No. It has no water, dust or splash resistance of any kind — no depth rating, no IP code, nothing published. This is the most important fact about it and the reason it should not be compared like-for-like with action cameras. Do not use it in rain, spray, snow or near water. If you need a weather-sealed Insta360 camera, the Ace Pro 2 is rated to 12m bare and the X6 to 20m (60m cased).
Which has the best video quality?
On published specifications the Luna Ultra: a 1-inch main sensor at F1.8 plus a 1/1.3-inch telephoto at F2.0, and 8K capture per Insta360's figures. The HERO13 Black's 1/1.9-inch sensor is the smallest here and the Action 5 Pro tops out at 4K120. But "best video quality" is only meaningful where the camera can go — and the Luna Ultra can't go anywhere wet, mounted or exposed to a drop. One caveat on the claim: Insta360 publishes no photo resolution figure for the Luna Ultra, so for stills it cannot be ranked against the HERO13 Black's 27.6MP at all.
Which has the best battery life?
The Luna Ultra and the Action 5 Pro tie at 240 minutes rated. GoPro publishes only >1.5 hours at 5.3K30 for the HERO13 Black's 1900mAh Enduro cell, which is not a like-for-like figure, so it cannot be ranked against them. On charging, the Luna Ultra reaches 80% in 23 minutes off a 45W charger; neither rival publishes a fast-charge figure.
Which is best for water sports?
The DJI Osmo Action 5 Pro, without qualification: 20m bare and 60m with its housing. The GoPro HERO13 Black is rated to 10m, which is fine for snorkelling and pool work and marginal below that. The Luna Ultra has no water resistance at all and must not be used for water sports in any form. If you want an Insta360 camera for water, the Ace Pro 2 is rated to 12m and the X6 to 20m.
Is the GoPro HERO13 Black still GoPro's flagship?
Not overall. GoPro did not release a HERO14 Black — for the first time in a decade it skipped the flagship HERO refresh and launched the MISSION 1 series instead, priced 20 April 2026 at $599.99 (MISSION 1) and $699.99 (MISSION 1 PRO), with a 50MP 1"-type sensor. The HERO13 Black is still the current HERO-line flagship and still sold at $429.99 (checked 28 September 2026), $170 less than the MISSION 1, which makes it the cheaper GoPro rather than a halo product. Any 2026 comparison presenting it as GoPro's top camera is out of date.
