Same idea, same lens specification, new numbers. The Pocket 4 keeps the Pocket 3's 1-inch sensor size, 20 mm f/2.0 lens and three-axis gimbal, and changes almost everything around them: slow motion, bitrate, storage, battery and screen. Here is what has changed, and who should still be happy with a Pocket 3.

Choose if: You are buying your first pocket gimbal, shoot slow motion, run out of card space or battery on long days, or film outdoors where screen brightness matters.
Choose if: You already own one and mostly film in normal 4K, rarely use slow motion, and do not run short of card space or battery. Its lens and gimbal format are the same.

Runtime for both is DJI's figure at 1080p/24 with Wi-Fi and the screen off. Pocket 4 figures from DJI's spec page and product page, checked 16 October 2026. The Pocket 3's zoom limits, colour profiles, storage and USB entries come from DJI's comparison on that product page.
Both cameras use a 1-inch sensor behind a 20 mm equivalent f/2.0 lens that focuses from 0.2 m, so framing and depth of field at a given distance are the same. What DJI changed is the sensor itself, which it calls new:
Winner: Pocket 4, clearly for photos. For video, both are 1-inch cameras with the same lens.
In normal video the two are level: 4K at up to 60 fps. The difference is in Slow Motion mode, where the Pocket 4 records 4K at 100, 120, 200 or 240 fps against a 4K120 maximum on the Pocket 3. At 240 fps one second of action stretches to eight seconds on a 30 fps timeline, twice the Pocket 3's four. The bitrate ceiling also rises from 130 to 180 Mbps.
The lossless 2x zoom is more usable on the Pocket 4: DJI excludes it only in Low-Light, Slow Motion and Timelapse, says it works with ActiveTrack and D-Log, and allows continuous zooming while recording. On the Pocket 3, DJI's footnote also rules it out with ActiveTrack, D-Log and Photo, and the ratio cannot be switched while recording. ActiveTrack moves from version 6.0 to 7.0, which DJI says keeps tracking at 4x zoom.
One open question: DJI's Pocket 4 product page says Slow Motion supports D-Log, while a footnote on the same page limits 10-bit D-Log to normal Video mode. Do not buy the Pocket 4 for graded 4K240 until DJI clarifies it.
Winner: Pocket 4, by twice the 4K slow-motion frame rate and 50 Mbps more bitrate.
Winner: Pocket 4 on every line except the first 80 % of a charge, which takes two minutes longer.
The Pocket 4 is 4.5 mm longer, 2.2 mm wider and 11.5 g heavier (190.5 g against 179 g); both are 33.5 mm deep. DJI does not say what the Pocket 4's weight includes. In a jacket pocket the difference is small, and the Pocket 4's battery holds 1.94 Wh more energy.
Winner: Pocket 3, narrowly.
If you use slow motion, run out of storage or battery, or want better photos, yes: 4K240 instead of 4K120, 107 GB built in, 240 instead of 166 minutes rated, and approximately 37 MP instead of 9.4 MP. If you film normal 4K at 60 fps or below and none of those limits bite, the Pocket 3's lens and gimbal format is the same, and the upgrade is smaller.
DJI's Pocket 4 product page lists the Pocket 4's own accessories (fill light, battery handle, ND and Black Mist filters) but does not say whether Pocket 3 accessories fit. The Pocket 4 is 4.5 mm longer and 2.2 mm wider, so cases and clip-on accessories made for the Pocket 3 may not. DJI Mic 2 transmitters do connect to both.
DJI publishes no low-light measurement for either, so there is no figure to compare. On the spec sheets, the Pocket 4's Low-Light Video mode reaches ISO 25,600 against 16,000 on the Pocket 3, and both use a 1-inch sensor behind an f/2.0 lens.
Only if you want a longer lens. The Pocket 4P adds a 60 mm f/1.8 tele camera for 3x optical zoom and a D-Log 2 profile DJI rates at up to 17 stops, but weighs 230 g and is rated for 210 minutes. See Pocket 4 vs Pocket 4P.
Buying new: The DJI Osmo Pocket 4 is the one to get. On DJI's figures it improves slow motion, bitrate, storage, runtime, screen brightness and stills resolution, for 11.5 g more.
Already own a Pocket 3: Upgrade if slow motion, storage or battery limit you today. If they do not, the Pocket 3 still shoots with the same lens format and gimbal.
