Want to see how the GoPro HERO4 Black matches up with Sony's New 4K Action Cam (FDR-X1000V)? We got our hands on both cameras and dug in for this video. In our Heads up video we compare sharpness and detail, color, dynamic range, menu, buttons, housings, battery life and mounts. Plus, steady shot, underwater, time-lapse, low-light and wind reduction test footage.
