Of course, the Sony X3000 action camera has optical stabilization, so it should be pretty unshakable too, but you'll just have to watch the video to find out how it does. 

The video is part of an action camera roundup The Wirecutter did earlier this year, which includes the GoPro Hero5 Black, the Sony FDR-X3000 that's used above, and the Yi 4K Action Camera, which was actually one of our favorites.
