Key Takeaways
- The Osmo Pocket 4 pairs a 1-inch CMOS sensor with a 20mm f/2.0 lens on a three-axis gimbal, in a body measuring 144.2 × 44.4 × 33.5 mm and weighing 190.5 g.
- The single biggest change from the Pocket 3 is still photography: maximum photo resolution rises from 3840×2160 to 7680×4320, and single-shot output from roughly 9.4 MP to roughly 37 MP.
- Video capture goes to 4K/240fps in slow motion, with a maximum bitrate of 180 Mbps and 10-bit D-Log available for grading.
- 107GB of built-in storage means no card is required to start shooting, though a microSD slot is present and accepts cards up to 1TB.
- Runtime is rated at 240 minutes under a specific test condition — 1080p/24, Wi-Fi off, screen off, 25°C. It is not a figure to expect at 4K or in the cold.
- There is no optical zoom and no water resistance rating. Zoom is digital (up to 4× in most video modes), and underwater use requires a separate housing.
The short answer
The Pocket 4 is a 1-inch-sensor gimbal camera that shoots 4K/240fps slow motion, captures roughly 37 MP stills, stores 107GB internally, and weighs 190.5 g. It has a 2-inch 1000-nit rotating touchscreen, three microphones, a 1545 mAh battery rated for 240 minutes of 1080p/24 recording, and Wi-Fi 6-class wireless.
The numbers below are taken from DJI's published specification sheet. Where a figure depends on a test condition, the condition is stated — a runtime or charging number without its conditions is not a specification, it is marketing.
After the table, there is a section on what the specs do not tell you, which matters more than the table itself.
Full specification sheet
Body and display
| Specification | Value | What it means in practice |
|---|---|---|
| Dimensions | 144.2 × 44.4 × 33.5 mm | Longer and slightly wider than the Pocket 3. Handle-shaped, so it is pocketable in a jacket rather than a jeans pocket. |
| Weight | 190.5 g | Heavier than the Pocket 3's 179 g. Noticeable over a long handheld session but not enough to change how you carry it. |
| Touchscreen | 2.0-inch, 556 × 314, 1000 nits | Same resolution as the Pocket 3 but 300 nits brighter, which is the difference between usable and unusable in direct sun. Rotates to face forward. |
| Microphones | 3 | Internal stereo capture plus support for wireless transmitters for multi-channel audio. |
| Storage card | microSD, up to 1TB | Optional. The 107GB internal storage covers most single-day shoots without one. |
Camera
| Specification | Value | What it means in practice |
|---|---|---|
| Sensor | 1-inch CMOS | The reason this camera exists. Roughly four times the light-gathering area of a typical phone sensor, which is what produces the low-light advantage. |
| Lens | 20 mm equivalent, f/2.0, focus from 0.2 m | Wide. Good for arm's-length self-shooting and interiors; poor for compressing distant subjects. Minimum focus of 20 cm allows close-up detail work. |
| ISO range (photo / video) | 50–12800 | Double the Pocket 3's upper limit. Useful headroom in dim rooms, though the top of any ISO range is a noise trade, not a free gain. |
| ISO range (low-light video) | 50–25600 | A dedicated mode with a higher ceiling. Expect visible noise at the top end; the point is that the shot exists at all. |
| Electronic shutter (photo) | 1/8000 to 4 s | The 4-second long exposure is new versus the Pocket 3's 1 second, and makes night stills practical without a separate camera. |
| Max photo resolution | 7680 × 4320 (16:9); 6144 × 6144 (1:1) | About 33 MP in 16:9. Enough to crop meaningfully, which is the main practical benefit of the resolution jump. |
| Single-shot output | ~37 MP | DJI's stated single-shot figure. Actual file size and detail depend on mode and processing. |
| Photo formats | JPEG / DNG / JPEG + DNG | DNG capture is available, which the Pocket 3 did not offer alongside JPEG. Relevant if you grade stills. |
Video
| Specification | Value | What it means in practice |
|---|---|---|
| Standard recording (16:9) | 4K 3840×2160 at 24/25/30/48/50/60fps; 1080p at the same frame rates | The everyday modes. 4K/60 is the practical ceiling for smooth handheld motion. |
| Vertical recording | 3K 1728×3072 and 1080p 1080×1920, 24–60fps | Native vertical capture without rotating in post. Aimed squarely at short-form platforms. |
| Slow motion | 4K at 100/120/200/240fps; 1080p at 120/240fps | The headline upgrade. The Pocket 3 topped out at 4K/120, so 4K/240 is double the slow-motion range at full resolution. |
| Low-light video | 4K and 1080p at 24/25/30fps | A separate mode, not an automatic behaviour. Frame rate is capped, which is the trade for the higher ISO ceiling. |
| Maximum bitrate | 180 Mbps | Up from 130 Mbps. More data per second means more latitude in grading and fewer compression artefacts in motion. |
| Video format | MP4 (HEVC) | HEVC only — the Pocket 3 also offered H.264. Older editing hardware may need transcoding. |
| Colour | 10-bit D-Log available | Grading latitude. Only worth using if you actually grade; otherwise it costs you time in post. |
| Timelapse modes | Motionlapse, Hyperlapse, static timelapse | Static intervals from 0.5 s to 60 s, durations from 5 minutes to unlimited. Motionlapse tracks up to 4 keyframes. |
| Zoom | Digital: 2× photo, up to 4× video (4K, 3K, 1080p) | Digital, not optical. It crops the sensor. Fine at 2×, visibly softer at 4×. Not available in slow motion, low-light video or timelapse. |
Gimbal
| Specification | Value | What it means in practice |
|---|---|---|
| Controllable range | Pan −235° to 58°; tilt −120° to 70°; roll −45° to 45° | The pan range is what allows the camera to follow a subject past 180°, which is the basis of the tracking features. |
| Max control speed | 180°/s | Fast enough to keep up with walking and moderate running. Not a substitute for a stabilised long lens. |
| Vibration suppression | ±0.005° | Manufacturer figure measured on a bench. Real-world smoothness depends far more on how you hold it. |
Battery and charging
| Specification | Value | What it means in practice |
|---|---|---|
| Battery | Li-ion, 1545 mAh, 11.95 Wh, 7.74 V | Larger than the Pocket 3's 1300 mAh. That capacity increase is where the runtime gain comes from. |
| Runtime | 240 minutes | Measured at 25°C, 1080p/24, Wi-Fi off, screen off. Shooting 4K, in cold weather, or with the screen on will produce materially shorter runs. |
| Charging | 18 min to 80%, 32 min to 100% | Measured with a DJI 65W charger, which is sold separately. A lower-wattage charger will be slower. |
| Operating temperature | 0°C to 40°C | Charging is restricted to 5°C to 45°C. Cold-weather shooting works; cold-weather charging may not. |
Connectivity
| Specification | Value | What it means in practice |
|---|---|---|
| Wi-Fi | 2.4 / 5.1 / 5.8 GHz, 802.11 a/b/g/n/ac/ax | Wi-Fi 6 support is new versus the Pocket 3's 802.11ac. Faster wireless offload on a compatible network. |
| Bluetooth | BLE 5.4, BR/EDR | Used for accessories and the app connection. Supports wireless microphone pairing. |
| Audio output | 48 kHz, 16-bit, AAC | Standard for this class. Four-channel recording is possible with compatible transmitters. |
Pocket 4 vs Pocket 3, side by side
Both cameras share the same sensor format and the same lens, so the generational difference is not where most people assume. It is in resolution, frame rates, storage and battery.
| Specification | Osmo Pocket 3 | Osmo Pocket 4 |
|---|---|---|
| Dimensions | 139.7 × 42.2 × 33.5 mm | 144.2 × 44.4 × 33.5 mm |
| Weight | 179 g | 190.5 g |
| Screen brightness | 700 nits | 1000 nits |
| Sensor | 1-inch CMOS | 1-inch CMOS |
| Lens | 20 mm, f/2.0 | 20 mm, f/2.0 |
| Max photo resolution | 3840 × 2160 | 7680 × 4320 |
| Single-shot output | ~9.4 MP | ~37 MP |
| ISO (photo / video) | 50–6400 | 50–12800 |
| ISO (low-light video) | 50–16000 | 50–25600 |
| Longest photo exposure | 1 s | 4 s |
| 4K slow motion | 120fps | 100/120/200/240fps |
| Max bitrate | 130 Mbps | 180 Mbps |
| Video codec | H.264 / HEVC | HEVC |
| Photo formats | JPEG / JPEG + DNG | JPEG / DNG / JPEG + DNG |
| Built-in storage | None | 107GB |
| Battery | 1300 mAh, 10.01 Wh | 1545 mAh, 11.95 Wh |
| Runtime (1080p/24) | 166 min | 240 min |
| Wi-Fi | 802.11 a/b/g/n/ac | 802.11 a/b/g/n/ac/ax |
Read this way, the Pocket 4 is not a different camera so much as a much more capable version of the same one. The sensor and lens are unchanged; everything around them got better. Whether that is worth an upgrade depends on whether you are limited by resolution, slow motion, runtime or storage — covered in the comparison article linked at the end of this page.
What the specs do not tell you
Five things a specification sheet cannot answer, all of which matter more than the numbers above.
1. Runtime is a lab figure. 240 minutes is 1080p/24 with the screen off and Wi-Fi off at 25°C. Shoot 4K/60 with the screen on in cold weather and the number will be substantially lower. Plan around roughly half the rated figure for demanding use, and carry a power bank.
2. Heat is the hidden limit. A one-inch sensor in a 190 g body has nowhere to put waste heat. The spec sheet lists no continuous recording limit, but small cameras in this class throttle. If you need long unbroken takes, test that specific scenario before relying on it.
3. Digital zoom is not zoom. Up to 4× in video sounds like a lens range. It is a crop of a 20mm field of view, so 4× leaves you with roughly a 5mm-equivalent angle and the resolution of one-sixteenth of the frame. At 2× it is usable; at 4× it is a convenience, not a substitute for reach.
4. There is no water resistance rating. No IP rating appears in the specification. DJI's own guidance is that underwater shooting requires a compatible housing and dry ports. Treat it as a fair-weather camera.
5. The gimbal numbers are bench figures. ±0.005° of vibration suppression says nothing about how steady your footage looks when you are walking. Footage smoothness comes from technique and from the tracking features, not from the suppression figure.
How long 107GB actually lasts
The storage figure is the one people misjudge most, because "107GB" sounds like a lot until you divide it by a bitrate.
Video is measured in megabits per second, storage in megabytes. Divide the bitrate by 8 to get megabytes per second, then divide the capacity by that. At the Pocket 4's maximum bitrate of 180 Mbps:
| Bitrate | Per second | 107GB holds |
|---|---|---|
| 180 Mbps (maximum) | 22.5 MB | about 81 minutes |
| 130 Mbps | 16.3 MB | about 112 minutes |
| 100 Mbps | 12.5 MB | about 146 minutes |
| 60 Mbps | 7.5 MB | about 243 minutes |
Two caveats. First, 180 Mbps is the ceiling, not the setting — actual bitrate depends on resolution, frame rate and scene complexity, so real recordings usually sit below it and the practical capacity is higher than the top row suggests. Second, the battery is the tighter constraint in most sessions: at roughly 240 minutes of rated runtime you will usually run out of power before you run out of space, unless you are shooting at maximum bitrate continuously.
The practical conclusion: 107GB is enough for a normal day without a card. It is not enough for a multi-day trip shooting 4K/60 all day, and it is nowhere near enough for a wedding or an event. That is when the microSD slot earns its place.

Frequently asked questions
What sensor does the DJI Osmo Pocket 4 use?
A 1-inch CMOS sensor behind a 20 mm equivalent f/2.0 lens with a minimum focus distance of 0.2 m. It is the same sensor format and lens specification as the Pocket 3.
What is the maximum video resolution and frame rate?
4K (3840×2160) at up to 60fps in standard recording, and 4K at up to 240fps in slow motion. 1080p slow motion also reaches 240fps. Maximum bitrate is 180 Mbps.
How much storage does the Pocket 4 have?
107GB of built-in storage, expandable through a microSD slot that accepts cards up to 1TB. No card is required to begin shooting.
How long does the battery last?
Rated at 240 minutes, measured at 25°C recording 1080p/24 with Wi-Fi and the screen off. Expect less at 4K, with the screen on, or in cold conditions. The battery is 1545 mAh / 11.95 Wh.
Does the Pocket 4 have optical zoom?
No. Zoom is digital — 2× for photos and up to 4× for video in 4K, 3K and 1080p. It crops the sensor rather than moving lens elements, and it is unavailable in slow motion, low-light video and timelapse modes.
Is the Pocket 4 waterproof?
No IP rating is published for it. Underwater shooting requires a compatible waterproof housing, and the ports must stay dry.
