With the launch of the Mini 4 Pro, DJI has nailed the recipe for producing premium-level ultralight drones. It comes just 18 months after the superb Mini 3 Pro, but with significant tweaks to the image processing and obstacle avoidance tech, it's undeniably the one to beat. At under 250 grams in weight, it's free from many of the rules and regulations that apply to larger models. In the USA there's no need to register it with the FAA for recreational use, while in the UK (a notoriously difficult place to fly drones), it can be flown pretty freely in public areas. Here in the UK, finding a sub-250 gram drone is critical for most amateur pilots.

Last year, DJI showed what was possible in a small drone with the Mini 3 Pro by fitting tons of technology and a high-quality camera into a sub-250 gram drone. Following that up was never going to be easy, but now (after numerous leaks) it's unveiled the Mini 4 Pro with a long list of new features. Aside from one improvement, the camera is largely the same. However, it has new omnidirectional obstacle sensors that eliminate the blind spots on the Mini 3 Pro. It also comes with a new feature called ActiveTrack 360 that lets you program camera moves when tracking a subject.
