Here is a quick comparison of the DJI Phantom 4 Pro and the DJI Mavic.

In terms of maneuvering, DJI has Active Track features in both the drones. It allows the pilot to tap and highlight a target on the controller screen and the drone will then follow. There is nearby-object detection sensors embedded in both.

The Mavic sports a 1/2.3-inch CMOS sensor with effect 12.35-megapixels that snaps in RAW and video up to 4K 4096 x 2160 at 24p. On the other hand, the Phantom 4 Pro features a full one inch CMOS sensor capable of hefty 20-megapixels effective that snaps in RAW and can shoot video at up to 4K 4096 x 2160 in 24/25/30p at 100Mbps. Phantom 4 takes it all with host of varying formats and qualities to suit any need.

The Phantom 4 Pro takes the lead with a top speed of 45 mph, which lasts for 30 minutes on a charge and can hit a height of 6,000 metres. Comparatively, the Mavic Pro hits 40mph top speed, which lasts for a decent 27 minutes on a single charge and tops out at 5,000 metres. 

Both feature Gesture Mode that lets you wave to activate the camera so you can take a selfie without the need to actually use the controller. Ascent and descent speeds are a little faster on the Phantom 4 Pro.

The Mavic folds down into a handheld compact unit that fits in its own safety case and weighs just 734 g. While, the Phantom 4 Pro, owing to its fixed size and shape, is less portable. It's also heavier at 1,388 g.

The DJI Phantom 4 Pro is priced higher at £1,600 while the DJI Mavic is a good chunk less at just under £1,100.

These are toys for some serious work and the choice of buyers can depend upon their use. The DJI Phantom 4 Pro is definitely a good take for outdoor action shoot.
