The DJI Inspire Pro model retails for $4500, and comes baseline with a 4K camera on a 3-axis stabilized gimbal. It’s a pretty good tool for filming. It’s maybe a less good tool for filming a concert live though, as Enrique Iglesias discovered when he grabbed onto a quadcopter at his show and was left with a bloodied hand. From the photos of the filming (there are 88 of them) it appears the singer kept a cool distance from her hovering minions. This isn’t Beyoncé’s first foray into technological frontiers; since 2005, she’s apparently maintained a digital archive of almost her entire waking life.
