Would you notice?
Mini 4K vs Mini 3: You would notice the sensor (1/2.3-inch CMOS vs 1/1.3-inch CMOS) in evening light; you would notice gimbal travel if you shoot vertical or roll. You would not really notice max video, flight time. UK: C0, stays under 250 g on every one of these. Flyer ID and Operator ID apply from 100 g with a camera — that is every drone here.

Questions
Will I notice the camera?
Mini 4K main: 1/2.3-inch CMOS · 12 MP · 24 mm, 4K/30. Mini 3 main: 1/1.3-inch CMOS · 48 MP · 24 mm, 4K/30 HDR. You would notice sensor class in low light; you would not notice the word 4K if both already do it.
Do I need to register the Mini 3 in the UK?
Mini 3 is C0, takeoff about 248 g (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. A Plus battery can take this out of C0 — weigh the pack you fly. 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 Mini 3 in the UK?
Mini 3 (C0): A1 Over People. May overfly uninvolved people; not crowds. Flyer ID + Operator ID from 100 g with a camera. 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).
Which is better at dusk?
Mini 3 on paper. Mini 4K is 1/2.3-inch CMOS with Downward; Mini 3 is 1/1.3-inch CMOS with Downward. Nightscape still needs texture and a minimum lux — it is not night vision.
Which is better for travel?
Mini 4K if the constraint is a bag and UK class (C0, 246 g). Mini 3 if you will accept C0 and 248 g for the bigger airframe.
Can I keep my Mini 4K batteries, controller or ND filters?
You can keep: DJI RC-N1. You cannot take: Mini 2 / Mini 4K Intelligent Flight Battery. Phone clamp for Mini 2, Mini 4K, Mini 3 family, Air 2, Air 2S and original Mavic 3. Does not fly Mini SE (Wi-Fi stick), Mini 4 Pro, Mini 5 Pro, Flip or Air 3.
How much more does it cost?
DJI UK RRP (as of 2026-08-31): Mini 4K £259, Mini 3 £319 — £60 more for the Mini 3. Street, eBay bands and CeX trade-in are on the board; they move.
Who should buy which?
Mini 4K: C0, 1/2.3-inch CMOS. Mini 3: C0, 1/1.3-inch CMOS.
