Comparison
DJI Mini 2 vs DJI Air 3
Would you notice?
Mini 2 vs Air 3: You would notice weight mostly as paperwork, bag mass and how close you may fly to people. You would not really notice wind. UK paperwork is part of the difference: Mini 2 is unmarked / sub-250 g (Flyer ID + Operator ID); Air 3 is C1 (Flyer ID + Operator ID).

Questions
Will I notice the camera?
Mini 2 main: 1/2.3-inch CMOS · 12 MP · 24 mm, 4K/30. Air 3 main: 1/1.3-inch CMOS · 48 MP · 24 mm, 4K/60 HDR, 4K/100. You would notice sensor class in low light; you would not notice the word 4K if both already do it. Optical telephoto is only on Air 3 — that is a different picture, not a sharper crop.
Do I need to register the Air 3 in the UK?
Air 3 is C1, takeoff about 720 g (C1. Flyer ID required.). In the UK a Flyer ID is required from 100 g, and an Operator ID is required from 100 g with a camera or from 250 g — this airframe needs both. This is not legal advice; read the CAA Drone Code for the airframe and battery you actually fly. Longer version: the UK Open explainer on this site (/guides/uk).
Do I need to register the Mini 2 in the UK?
Mini 2 is unmarked, takeoff about 242 g (DJI standard takeoff 242 g with battery, props and a microSD card. Marketed under 249 g.). In the UK a Flyer ID is required from 100 g, and an Operator ID is required from 100 g with a camera or from 250 g — this airframe needs both. This is not legal advice; read the CAA Drone Code for the airframe and battery you actually fly. Longer version: the UK Open explainer on this site (/guides/uk).
How far from people can I fly the Air 3 in the UK?
Air 3 (C1): A1 Over People (C1 until 31 Dec 2027). May overfly uninvolved people; not crowds. Flyer ID + Operator ID. Remote ID on from 1 Jan 2026 (C1 as UK1). Towns OK in A1. Open height is 120 m AGL. Never over crowds. This is not legal advice — the CAA Drone Code (March 2026) applies to the airframe and battery you actually fly. Longer version: the UK Open explainer on this site (/guides/uk).
How far from people can I fly the Mini 2 in the UK?
Mini 2 (unmarked): A1 Over People. No class mark. CAA legacy weight table: under 250 g is A1 — same Open subcategory as C0. May overfly uninvolved people; not crowds. Flyer ID + Operator ID from 100 g with a camera. Open height is 120 m AGL. Never over crowds. This is not legal advice — the CAA Drone Code (March 2026) applies to the airframe and battery you actually fly. Longer version: the UK Open explainer on this site (/guides/uk).
Which is better in wind?
Air 3 carries more mass into DJI’s published wind figure (Mini 2 10.5 m/s, Air 3 12 m/s). On a UK headland that is often the whole decision. Lab Level numbers that match can still feel different because weight is not in the level name.
Which is better at dusk?
Air 3 on paper. Mini 2 is 1/2.3-inch CMOS with Downward; Air 3 is 1/1.3-inch CMOS with Omnidirectional. Nightscape still needs texture and a minimum lux — it is not night vision.
Which is better for travel?
Mini 2 if the constraint is a bag and UK class (unmarked, 242 g). Air 3 if you will accept C1 and 720 g for the extra camera.
Can I keep my Mini 2 batteries, controller or ND filters?
These do not share a battery family. Plan to buy packs, and check ND thread and RC protocol — Mini 4 Pro filters and batteries do not sit on a Mini 5 Pro.
How much more does it cost?
DJI UK RRP (as of 2026-08-31): Mini 2 —, Air 3 £869. Used and CeX sit on the price board below — some of these are discontinued as new.
Who should buy which?
Mini 2: unmarked, 1/2.3-inch CMOS. Air 3: Dual camera and wind; you accepted C1.
