Upgrading From a DJI Mini 3: Mini 5 Pro or Air 3S?

If you own a DJI Mini 3, the upgrade question is Mini 5 Pro vs Air 3S. Both have a 1-inch main sensor, both add the obstacle sensing the Mini 3 never had, and both shoot 4K/120. The real difference is weight and lenses: the Mini 5 Pro stays at about 249.9 g with one camera, while the 724 g Air 3S adds a 70 mm telephoto and must be registered in the US.

What both upgrades fix over the Mini 3

Either drone changes the same three things. The sensor grows from 1/1.3-inch to 1-inch, which shows most at dusk and in high-contrast light. Video goes from 4K/30 in 8-bit to 4K/60 HDR and 4K/120 with 10-bit D-Log M and HLG, so footage can actually be graded. And both add omnidirectional obstacle sensing with a forward LiDAR sensor. The Mini 3 only senses downward, for hovering and landing.

Transmission also moves from O2 (720p feed, 10 km FCC) to O4 (1080p feed, 20 km FCC), and both are rated for 12 m/s wind against the Mini 3’s 10.7 m/s.

One thing that does not carry over: your batteries. Mini 3 packs work in a Mini 4 Pro, but not in the Mini 5 Pro, which uses its own 2,788 mAh battery, or in the Air 3S.

Mini 5 Pro: same size, better camera

In the Mini 5 Pro vs Air 3S choice, the Mini 5 Pro is the upgrade that changes nothing about how you carry the drone. It folds to the same pocketable size, its gimbal rolls far enough for true vertical video like the Mini 3’s, and it has 42 GB of internal storage.

The weight is less tidy than the 249.9 g headline. DJI quotes a ±4 g tolerance and DroneXL reports production units at 252–253 g, so I would plan on registering it with the FAA ($5) rather than count on the exemption.

Buying it is the bigger catch. DJI never launched the Mini 5 Pro in the US, so Amazon US listings come from retailers rather than DJI, and its LiDAR puts it in scope of the FCC’s pending proposal on “military-grade” foreign drones. Our explainer on the LiDAR proposal covers what that could mean.

Air 3S: a second lens and longer flights

The Air 3S adds what no Mini has: a 70 mm medium telephoto with its own 48 MP 1/1.3-inch sensor. It lets you compress a scene, shoot from farther away and frame subjects without flying closer. It also flies longer, up to 45 minutes, and is a steadier platform in wind.

The trade-off is size and paperwork. At 724 g it must be registered with the FAA and broadcast Remote ID, recreational flying included, and in the EU it falls under stricter rules than a sub-250 g drone. It also uses LiDAR and is named in DJI’s own comments on the FCC proposal, but unlike the Mini 5 Pro it was authorized and sold in the US.

Mini 5 Pro vs Air 3S: which upgrade should you buy?

For most Mini 3 owners in the US weighing Mini 5 Pro vs Air 3S, I think the Air 3S is the safer pick: it is the one sold normally there, and the telephoto is a genuinely new tool rather than a better version of what you have. The Mini 5 Pro makes more sense if you live where DJI sells it officially and pocket size is the reason you bought a Mini in the first place.

• Mini 5 Pro: you travel light, shoot mostly scenery and social video, and want the smallest drone with a 1-inch sensor.
• Air 3S: you want a telephoto, longer flights and steadier footage in wind, and you don’t mind registering it.
• Mini 4 Pro: a cheaper step if you mainly want obstacle sensing and 4K/60 HDR. It keeps the Mini 3’s 1/1.3-inch sensor size and has omnidirectional vision without LiDAR.
