Your drone should not have to be as large as a movie studio to capture quality video for you. The DJI Mavic Pro ($1K) drone is quite powerful enough to give you one of the most sophisticated flying camera systems in the air today.
The Mavic’s Intelligent Flight batteries allow a flight time of up to 27 minutes with a range of up to 8 miles. Monitoring with the DJI GO app allows real-time battery and estimated flight time remaining information. A duel redundant sensor system can detect and avoid obstacles from as far as 50 ft away and lets the DJI Mavic Pro hover with stable altitude automatically.
A special 3-axis gimbal stabilizes the camera shooting 4K video at 30 fps. Using the tap-fly system, this drone is easy to fly even for beginners so they can concentrate on shooting video. It also folds up nicely for easy transportation between flights.
