DJI Osmo Pocket 4 Review
DJI's fourth pocket gimbal keeps the 1-inch sensor size and the 20 mm f/2.0 lens of the Pocket 3, and raises nearly every number around them: 4K slow motion at up to 240 fps, 107 GB of built-in storage, a 1000-nit screen and a 240-minute rated runtime. It is the one-camera answer for vloggers who want gimbal-smooth footage without carrying a gimbal.

The Verdict
The Osmo Pocket 4 is a 1-inch-sensor camera on a three-axis mechanical gimbal, small enough to hold in one hand and announced by DJI on 16 April 2026. It is built for people who film themselves: travel and daily vloggers, creators who shoot vertical clips for social media, and anyone who wants stabilised walking footage without carrying a separate gimbal.
Against the Pocket 3, the gains are concrete on DJI's own sheet: 4K slow motion doubles to 240 fps, the bitrate rises from 130 to 180 Mbps, 107 GB of storage is now built in, and the rated runtime grows from 166 to 240 minutes under the same test settings (1080p/24, Wi-Fi and screen off). Choose it over the Pocket 4P if one 20 mm lens covers what you film: the 4P, with its added 3x tele camera, weighs 39.5 g more and is rated 30 minutes shorter.

What Stands Out
- 4K slow motion at up to 240 fps, twice the Pocket 3's 4K120
- 107 GB built in plus microSD up to 1 TB; DJI quotes up to 800 MB/s wired export over USB 3.1
- 240 minutes rated runtime (Pocket 3: 166) and 80 % charge in 18 minutes with DJI's 65 W charger
- 2-inch rotating OLED screen rated at 1000 nits, up from 700 on the Pocket 3
- DJI Mic 2, Mic 3 and Mic Mini transmitters connect directly, for four-channel audio
- 2x lossless zoom now works in more modes, and ActiveTrack 7.0 follows subjects at up to 4x zoom
Trade-offs
- 4K240 is a Slow Motion mode only; normal video tops out at 4K60
- DJI's own pages disagree on whether D-Log works in Slow Motion
- One fixed 20 mm lens; all zoom is digital (2x lossless, up to 4x in video)
- DJI publishes no water or dust rating, and rates operation at 0 to 40 °C
- DJI lists audio as 48 kHz 16-bit AAC, a compressed format
In Depth
Sensor, lens and colour
DJI describes the sensor as a new 1-inch CMOS and pairs it with the same lens specification the Pocket 3 had: 20 mm equivalent at f/2.0, focusing from 0.2 m. DJI does not publish the sensor's size in millimetres or an effective pixel count; it lists single shots at approximately 37 MP, with a largest image of 6144 × 6144 at 1:1. The Pocket 3 shot approximately 9.4 MP.
For grading, DJI names a 10-bit D-Log profile and quotes 14 stops for both the Normal and D-Log profiles, adding that Slow Motion may deliver less. HLG is not mentioned on the Pocket 4's spec or product page; HDR 10-bit video is. One point DJI leaves unresolved: the product page says Slow Motion supports D-Log, while a footnote on the same page says 10-bit D-Log works only in normal Video mode. Until DJI settles it, plan on log footage at up to 4K60 in normal video.
Frame rates and slow motion
Normal video runs at 24 to 60 fps in 4K and 1080p, and the Pocket 4 records vertical video at 3K (1728 × 3072) or 1080p in 9:16, so a portrait clip comes out of the camera as a 9:16 file instead of being cropped in editing. The high frame rates sit in a separate Slow Motion mode: 4K at 100, 120, 200 or 240 fps, and 1080p at 120 or 240 fps. At 240 fps, one second of action plays back as eight seconds at 30 fps.
Everything is recorded as HEVC in MP4, at up to 180 Mbps. Low-Light Video is a separate mode capped at 30 fps that opens the ISO ceiling from 12,800 to 25,600. Digital zoom reaches 4x in video, but none of it is available in Low-Light, Slow Motion or Timelapse.
Gimbal, tracking and zoom
The three-axis gimbal has a controllable pan range of −235° to 58°, moves at up to 180°/s and is specified to an angular vibration range of ±0.005°. DJI calls the focusing system Intelligent AF and does not say whether it uses phase detection. On top of it sit Subject Lock Tracking (tap a detection box to switch subjects) and Registered Subject Priority, which gives priority to a subject you have registered in advance.
ActiveTrack 7.0 is DJI's subject-following mode; DJI says it keeps tracking distant subjects at 4x zoom, with Spotlight Follow, Dynamic Framing and Frame Tracking as options. It is not available in Panorama, Timelapse, Motionlapse or SpinShot. DJI excludes the 2x lossless zoom only in Low-Light, Slow Motion and Timelapse, and says it works with ActiveTrack and D-Log and zooms continuously while recording. Its footnote for the Pocket 3 excludes ActiveTrack, D-Log and Photo modes as well, and says the zoom ratio cannot be switched during recording there.
Audio, storage and power
Three built-in microphones handle sound on their own, with spatial audio and an audio zoom that follows the image zoom. DJI Mic 2, Mic 3 and Mic Mini transmitters connect without a receiver; with one connected, the Pocket 4 records four channels, so the voice and the built-in ambient track arrive as separate tracks for editing. The first-generation DJI Mic is not supported. The audio itself is 48 kHz 16-bit AAC.
The 107 GB of internal storage means a forgotten card no longer ends the day, and a microSD card up to 1 TB adds more. DJI quotes up to 90 MB/s over Wi-Fi and, in a lab test, 800 MB/s over a USB 3.1 cable. The 1545 mAh battery is rated for 240 minutes at 1080p/24 with Wi-Fi and the screen off, a light load; DJI gives no figure for 4K with the screen on. For live work there is 1080p Wi-Fi livestreaming through the DJI Mimo app, and PC streaming over UVC or the 4K DisplayPort output (the latter needs a capture card).

FAQ
Should I buy the Pocket 4 or the Pocket 4P?
The 4P adds a second camera: a 60 mm equivalent f/1.8 tele on a 1/1.28-inch sensor, with 3x optical zoom and up to 12x zoom in video. Its main 1-inch camera is rated by DJI at up to 17 stops in D-Log 2, and it gets ActiveTrack 8.0. In exchange it weighs 230 g instead of 190.5 g, and DJI rates it for 210 minutes instead of 240. If you mostly film yourself at arm's length, the 20 mm lens of the Pocket 4 is the one you would use anyway.
Is it worth upgrading from the Pocket 3?
On DJI's figures, the upgrade is largest if you use slow motion, run out of card space or battery, or shoot photos: 4K240 instead of 4K120, 180 instead of 130 Mbps, 107 GB built in, 240 instead of 166 minutes of rated runtime, and approximately 37 MP stills instead of 9.4 MP. The lens specification (20 mm, f/2.0) and the 2-inch screen size are unchanged.
Can the Pocket 4 record D-Log in slow motion?
DJI's pages contradict each other. The Pocket 4 product page says Slow Motion supports D-Log, a footnote on the same page says 10-bit D-Log works only in normal Video mode, and the Pocket 4P page states that the Pocket 4 supports D-Log in both normal Video and Slow Motion. If log footage at high frame rates is the reason you are buying, the Pocket 4P is the model for which DJI states it without contradiction.
Is the Pocket 4 waterproof?
DJI's spec sheet has no water or dust rating for the Pocket 4, so treat it as an unsealed camera with an exposed gimbal. DJI also rates it for operation between 0 and 40 °C. For water, rain or snow, an action camera such as the Osmo Action line is the safer tool.
Final Recommendation
The Osmo Pocket 4 keeps the Pocket 3's format and, on paper, improves the parts that limit a day of filming: storage, runtime, slow motion and screen brightness. Unless you need a longer lens, it is the Pocket to buy.
Buy it if: You film yourself while walking or travelling, post vertical video, want 4K slow motion in a pocketable camera, or want DJI Mic transmitters to connect without a receiver.
Skip it if: You want an optical tele for portraits or distant subjects (look at the Pocket 4P), need log footage in slow motion with certainty, film in water or freezing weather, or already own a Pocket 3 and do not use slow motion or run out of storage.
