The big announcement is that the Phantom has an obstacle sense and avoid system, provided you're flying forwards. It's the first technology like it on a consumer quadcopter. DJI's own Matrice, designed for commercial clients, has an all round collision avoidance system as an optional extra. If the Phantom detects an obstacle it will try to fly over or around it. If neither of those is an option, it will stop and hover. The vision positioning system from the P3 has been improved too.
Then there's target tracking and TapFly. If you want to follow something or someone all you have to do is draw around the outline on the tablet screen and the Phantom will keep your camera shot centred on your chosen subject. If you fancy flying straight to a location you can tap on the screen and send the Phantom flying straight to it.
Performance has been improved too. There's a new Sports mode that can be selected on the controller which allows you to push the Phantom 4 nearer its limits once you've gained some experience and confidence. It is capable of reaching 45 mph, which is the same sort of speed as the bigger Inspire 1. Battery life has been increased too. Instead of 23 minutes maximum flight time, the Phantom 4 now boasts 28. The battery capacity has increased - up from 4480 mAh to 5350 mAh.
From a safety point of view DJI have introduced a dual compass and IMUs (Inertial Measurement Units). This introduces a level of redundancy and also allows the Phantom to better handle potential errors.
There are improvements on the camera too. Although it's very similar to the Phantom 3 Professional, the camera on the 4 has 56% less chromatic aberration. That's the annoying coloured fringing you can get on the border between bright and dark areas of pictures. There's also a claimed 36% reduction in lens distortion even though the field of view is still 94 degrees.
The video slo-mo has also been improved. In 1080 HD the camera will shoot at 120 fps meaning you'll be able to play back at a quarter of normal speed.
The camera gimbal appears to be sturdier, with a U-shaped mount supporting the camera.
The props are easier to attach and more likely to stay attached. They use the same mechanism employed on the latest Inspire - just push the prop into place and turn a locking catch.
