Key Takeaways
- The sensor and lens are unchanged. Both cameras use a 1-inch CMOS behind a 20 mm f/2.0 lens, so the generational difference is not image character — it is resolution, frame rates, storage and battery.
- Stills are the largest single jump: maximum photo resolution rises from 3840×2160 to 7680×4320, and single-shot output from roughly 9.4 MP to roughly 37 MP.
- Slow motion doubles at full resolution: 4K/120 on the Pocket 3 becomes 4K/100/120/200/240 on the Pocket 4, with the bitrate ceiling rising from 130 to 180 Mbps.
- The Pocket 4 adds 107GB of internal storage and a 1545 mAh battery rated for 240 minutes, against no internal storage and 166 minutes on the Pocket 3.
- Availability is the biggest practical difference for US buyers. The Pocket 3 has a normal US retail and warranty path; the Pocket 4 does not, and every US unit is third-party stock.
- For 4K/60 handheld video, the upgrade case is weak. For stills, 4K/240 or all-day recording, it is straightforward.
The short answer
If you already own a Pocket 3 and shoot mostly 4K/60 handheld video, the Pocket 4 does not change what you can make. The sensor and lens are the same, so the footage looks the same; you would be paying for stills resolution, 4K/240 slow motion, internal storage and runtime.
If you shoot stills, slow motion, or long unbroken sessions, the Pocket 4 is a substantial step and the Pocket 3 is the wrong camera to buy today.
If you are buying new in the US and have no existing kit, the decision is less about specs than about channels. The Pocket 3 is sold through normal US retail with DJI's US warranty. The Pocket 4 has no official US channel, so every unit is third-party stock with a seller-level warranty instead. That trade is the real comparison, and it is covered in the second half of this article.
Two questions, one article
Search results for this comparison usually answer neither question well, because the two readers asking it want opposite things. So the article splits: the first half is for people who own a Pocket 3 and are deciding whether to spend again. The second half is for people buying their first gimbal camera in the US, for whom availability may matter more than any row in the spec table.
Specifications, side by side
| Specification | Osmo Pocket 3 | Osmo Pocket 4 | What it changes in practice |
|---|---|---|---|
| Sensor | 1-inch CMOS | 1-inch CMOS | No change. Same light-gathering area, same low-light starting point. |
| Lens | 20 mm equivalent, f/2.0 | 20 mm equivalent, f/2.0 | No change. Same field of view, same perspective, same framing habits. |
| Dimensions | 139.7 × 42.2 × 33.5 mm | 144.2 × 44.4 × 33.5 mm | 4.5 mm longer and 2.2 mm wider. Cases and clamps are not interchangeable. |
| Weight | 179 g | 190.5 g | 11.5 g heavier. Noticeable over a long handheld session, not decisive. |
| Screen brightness | 700 nits | 1000 nits | The difference between usable and unreadable in direct sun. One of the most practical changes. |
| Max photo resolution | 3840 × 2160 | 7680 × 4320 | Four times the pixel count. Enough to crop a still meaningfully, which the Pocket 3 could not do. |
| Single-shot output | ~9.4 MP | ~37 MP | Stills become a real use case rather than a screenshot of the video feed. |
| Photo formats | JPEG / JPEG + DNG | JPEG / DNG / JPEG + DNG | DNG on its own is now an option, which matters if you grade stills. |
| ISO, photo and video | 50–6400 | 50–12800 | One stop more headroom in dim rooms, at the cost of noise at the top of the range. |
| ISO, low-light video | 50–16000 | 50–25600 | A dedicated mode with a higher ceiling, capped to 24/25/30fps. |
| Longest photo exposure | 1 s | 4 s | Night stills without a second camera. A small row with a large practical effect. |
| 4K slow motion | 120fps | 100/120/200/240fps | Double the range at full resolution. 240fps at 4K is the headline capability. |
| Maximum bitrate | 130 Mbps | 180 Mbps | More latitude in grading and fewer artefacts in fast motion. |
| Video codec | H.264 / HEVC | HEVC only | A regression for older editing hardware. The Pocket 3 could fall back to H.264; the Pocket 4 cannot. |
| Built-in storage | None | 107GB | No card needed to start. The Pocket 3 required one before the first shot. |
| Battery | 1300 mAh, 10.01 Wh | 1545 mAh, 11.95 Wh | 19% more capacity, which is where most of the runtime gain comes from. |
| Runtime at 1080p/24 | 166 min | 240 min | Both are lab figures at 25°C with the screen and Wi-Fi off. The ratio is what transfers, not the number. |
| Wi-Fi | 802.11 a/b/g/n/ac | 802.11 a/b/g/n/ac/ax | Faster offload on a Wi-Fi 6 network. Irrelevant if you use a cable. |
| Zoom | Digital crop | Digital crop, with a 2× lossless mode listed by DJI | Same lens, so this is crop quality rather than reach. Neither camera has optical zoom. |
Read the table as two columns of change: everything about capture got better, and nothing about the optics changed. That single observation explains most of the upgrade decision below.
The four changes that matter
1. Stills went from incidental to usable
At 3840×2160, the Pocket 3's stills were about 8.3 MP by pixel count — DJI's single-shot figure was roughly 9.4 MP — enough for a social post, not enough to crop. At 7680×4320 the Pocket 4 produces roughly 33 MP in the same aspect, with a single-shot figure around 37 MP. Combined with a 4-second maximum exposure and DNG capture, that turns the camera into something you can hand to a photographer without an explanation.
If you shoot any stills at all, this is the row that justifies the upgrade on its own. If you shoot only video, skip to the next section, because nothing else here will change your work as much.
2. 4K/240 is a different tool, not a better one
The Pocket 3 tops out at 4K/120. The Pocket 4 reaches 4K/240, which is a 10× slow-down at 24fps output. That is the difference between a slow-motion shot and a shot where a water droplet's shape is visible. It is also the feature most likely to be bought and rarely used, because 240fps needs light and a subject worth stretching.
An honest test: if you have not used 4K/120 on the Pocket 3 in the last three months, you will not use 4K/240 either.
3. 107GB removes a daily friction
Every Pocket 3 owner has the same first-task ritual: buy a card, format it, watch the remaining-time counter. The Pocket 4 ships with 107GB of internal storage, so the ritual disappears. At the maximum 180 Mbps that is roughly 81 minutes of recording; at 60 Mbps, roughly 243 minutes. For a normal shooting day it is enough to start without a card at all.
This is the least glamorous change and, in daily use, probably the most felt one.
4. Runtime and screen brightness compound
240 minutes against 166 is a 45% increase in rated runtime, and 1000 nits against 700 is the difference between framing on a screen and guessing at it outdoors. Neither is a headline feature. Together they change how long you can shoot and how confidently, which is what most people actually complain about after a year with a small camera.
The three things that did not change
The optics. Same sensor format, same 20 mm f/2.0 lens. If your complaint with the Pocket 3 was the field of view, the Pocket 4 does not answer it. Neither camera has optical zoom; the Pocket 4's 2× mode is a crop of the same lens, which preserves quality better than a naive crop but does not add reach.
The stabilisation class. Both are three-axis gimbal cameras of the same generation of design. The Pocket 4 adds tracking behaviour that works at longer zoom settings, which is useful, but it is not a different stabilisation technology.
The form factor. 4.5 mm longer and 11.5 g heavier is a specification change, not an ergonomic one. It is worth knowing because accessories are not cross-compatible: cases, clamps and cages built for the Pocket 3 do not fit the Pocket 4.
Where the Pocket 3 still wins
Five points, and they are not consolation prizes.
It has a normal US retail path. The Pocket 3 was certified for US sale before the regulatory change that affects the Pocket 4, so it is available through ordinary retail with DJI's US warranty behind it. For a buyer who values a straightforward service route over specifications, that is a genuine advantage.
It is cheaper. DJI launched the Pocket 3 in the US at $519 for the Standard Combo and $669 for the Creator Combo, and street prices have moved down since — our own US price guide puts the Standard Combo at around $419 on ordinary retail channels. Against the Pocket 4's $560, that is roughly $140, before any accessory spend.
It is lighter. 179 g against 190.5 g, in a product whose entire appeal is being carried.
It offers H.264. If you edit on older hardware, HEVC-only on the Pocket 4 means transcoding every clip. That is a real workflow cost the spec table states plainly and most comparisons ignore.
Its accessory ecosystem is mature. Three years of cases, cages, filters and mounts exist for the Pocket 3. The Pocket 4 is new, and the accessories that fit it are fewer and more expensive per unit.
The upgrade decision, by what you shoot
| If this is your main use | Verdict | Why |
|---|---|---|
| Talking-head and vlog video at 4K/30–60 | Not worth upgrading | Same sensor, same lens, same look. The Pocket 3 already does this well. |
| Travel and walking footage | Not worth upgrading | Weight goes up and the optics do not change. The 107GB storage is the only daily gain. |
| Stills, especially anything you crop or print | Worth upgrading | 9.4 MP to 37 MP, plus DNG and a 4-second exposure. This is a different camera for stills. |
| Slow motion as a recurring technique | Worth upgrading | 4K/240 against 4K/120, with a higher bitrate ceiling. |
| Long event or documentary sessions | Worth upgrading | 240 minutes against 166, plus internal storage that removes card swaps mid-session. |
| Outdoor shooting in bright sun | Worth considering | 1000 nits against 700 is a real usability change, but it is one feature, not a case on its own. |
| You edit on an older machine | Consider staying | HEVC-only capture means transcoding. Budget for that cost before upgrading. |
The pattern is simple. The Pocket 4 is a video camera with a stills camera attached that finally works. If you do not need the stills, the slow motion or the runtime, the Pocket 3 remains a competent 4K/60 gimbal camera with better availability in the US.
If you are buying new in the US
This is the part that changes the decision for most first-time buyers, and it has nothing to do with specifications.
The Pocket 4 has no official US sales channel. DJI was added to the FCC Covered List on 2025-12-22, and the practical consequence is that no US retailer holds an official DJI distribution path for this model. Every Pocket 4 sold in the US, including ours, is third-party stock. The Pocket 3 predates that change and is sold through normal US retail.
So the comparison is not "newer versus older". It is "third-party stock with a seller-level warranty" against "normal retail with the manufacturer's US warranty". Both are legitimate choices, and which one is right depends on how much you value the warranty path versus the capability jump.
| Option | Price | Warranty path | Availability in the US |
|---|---|---|---|
| Osmo Pocket 4, Standard Combo (POCKET HUB) | $560 | 1-year limited warranty from the retailer, from the delivery date | Independent US retailer; ships from Hong Kong with duties and taxes included, 3–5 business days after dispatch |
| Osmo Pocket 4, Creator Combo (POCKET HUB) | $799 | 1-year limited warranty from the retailer, from the delivery date | Same |
| Osmo Pocket 3, Standard Combo | Around $419 on US retail channels; launch price $519 | DJI US warranty through normal retail | Ordinary US retail channels |
| Osmo Pocket 3, Creator Combo | Launch price $669; street price varies | DJI US warranty through normal retail | Ordinary US retail channels |
Two things worth stating plainly about the Pocket 4 column. First, we are an independent US retailer, not part of DJI's distribution network, so the warranty you rely on is ours rather than DJI's — it is a 1-year limited warranty that runs from delivery and is administered by us. Second, the price includes duties and taxes for US delivery, and a unit confirmed non-genuine is refunded rather than replaced, because a replacement would not answer the question the buyer asked.
If DJI's own US warranty is the thing you value most, the Pocket 3 is the only one of the two that offers it, and no amount of specification advantage on the Pocket 4 changes that. If you want the stills, the 4K/240 and the internal storage, the Pocket 4 is the only one that has them, and the trade is a retailer warranty instead of a manufacturer one.
POCKET HUB · Independent US retailer
Standard Combo $560 · Creator Combo $799
Duties included. 1-year stated warranty on non-user-caused faults, 14-day returns, and a full refund if the serial number fails verification against DJI’s own records.
Frequently asked questions
Is the Pocket 4 worth upgrading from the Pocket 3?
For stills, 4K/240 slow motion or long recording sessions, yes — those are substantial changes. For 4K/30–60 talking-head or travel video, no: the sensor and lens are identical, so the footage looks the same.
Do the Pocket 3 and Pocket 4 use the same sensor?
Yes. Both use a 1-inch CMOS sensor behind a 20 mm equivalent f/2.0 lens. The difference is in processing, resolution, frame rates, storage and battery, not in the optics.
Are Pocket 3 accessories compatible with the Pocket 4?
No. The Pocket 4 is 4.5 mm longer and 2.2 mm wider, so cases, clamps and cages built for the Pocket 3 do not fit. Plan for new accessories if you switch.
Does the Pocket 4 have optical zoom?
No. It uses a digital crop, with a 2× lossless mode listed by DJI. Because the lens is the same 20 mm f/2.0 as the Pocket 3, the zoom range is a crop of the same field of view rather than additional reach.
Why is the Pocket 4 not sold through normal US retail?
DJI was added to the FCC Covered List on 2025-12-22, which affects the authorisation path for new devices. The Pocket 3 predates that change and is sold through ordinary US retail. Every US Pocket 4, including ours, is third-party stock.
Is the Pocket 3 still a good buy in 2026?
For 4K/60 handheld video, yes. It has the same sensor and lens, a lighter body, H.264 support and a normal US warranty path. It is the weaker choice for stills, slow motion and all-day recording.
