DJI is known for their quadcopters no doubt. They, in my opinion, are the most reliable quads on the market today. Now they are applying their proven 3-axis stabilization to a handheld gimbal, the DJI Osmo ($649) with a 4k camera along for the ride. The camera shoots 4K video and up to 120fps at 1080P. Heck you can even put a better camera/lens on the stabilizer if that is your thing.
There is a joystick for full pan and tilt control as well as trigger for switching between modes (upright, selfie, flashlight, locked, and underslung). Heck you can even shoot automatic panoramas and time-lapse videos. Apparently I am not the only one hitting the DJI website as it is currently down. Ouch. Again, Apple please buy these guys.
