More to consider
1) Inspire style Metal device holder arm
2) A new, specially designed, magnesium core increases the stiffness and rigidity of the Phantom 4 without compromising weight.
3) Shoot sharp, clean video in up to 4K at 30fps and Full HD 1080p at 120fps for slow motion, through a
newly designed 8 element lens that
dramatically increases sharpness.
4) Dual compass modules and dual Inertial Measurement Units (IMUs)
5) Motors located higher --No more props in video when accelerating.
6) Slightly increased flight time
7) Faster --- New Sport mode
8) The gimbal and camera system is integrated into the body, bringing it closer to the aircraft's center of gravity.
It is also made of a rigid and strong composite material
9) The Phantom 4 camera has been improved in terms of image quality. Chromatic aberration has been reduced by 56% and lens distortion had been reduced by 36% compared to Phantom 3 Professional. In addition to lens improvements, camera firmware has been tweaked to enable the camera to capture 120fps video in full 1080p FHD (the camera’s field of view will be reconfigured to 47° when recording in this mode) for smooth slow motion.
