💡 In a few words.
The Phantom 4's new stockier design sees the old plastic body replaced with a sleek magnesium alloy, finished in glossy white. The camera and gimbal design are improved, and are better integrated into the body, making the whole setup feel more robust.
Essentially the camera remains much the same as on the Phantom 3 Professional. It has a 1/2.3-inch sensor and an f/2.8 lens with a 94 degree field of view and an equivalent 35mm focal length of 20mm. However, the specifications of the 4K camera bring a few resolution and frame rate improvements.
At 1080p the camera takes a leap from a maximum of 60fps to 120fps. There's also a change to the top end resolutions and frame rates, with an additional 3840 x 2160 (4K) option alongside the existing 4096 x 2160 (4K), and a new 2704 x 1520 (2.7K) option.
As with the 3 Professional, the 4 features the ground-facing positioning cameras that help to stabilise the flight of the drone. These cameras are now joined by two front-facing sensors that are able to detect objects in the drone's flight path.
Short battery life has been an issue with previous Phantoms, and DJI has moved to address this in the Phantom 4 with a battery that extends flight times by a quoted 25%.
