DJI are the biggest brand in consumer drones, but has held out against offering 4K video at the entry-level a bit longer than some – instead settling on three tiers in the 'ultralight' (below 250g) drone. The models change, but at the time of this launch, these are the entry-level Mini 2 SE, the Mini 3 which has a better camera, and the Mini 4 Pro which sports a lot of serious features and omni-directional collision sensors. The drone with 'SE' topped out at 2.7K resolution.
The new Mini 4K is not very different from the Mini 2 SE in terms of design; the airframe is the same and it takes the same batteries. If it wasn't for the name on the side it'd you'd probably not be able to tell the difference. Switch them on, however, and the Mini 4K has a good few more options in the camera resolution menu.
