All the big action camera manufactures have new, improved models out-and just in time for the holidays, what a coincidence! And again, they all make the same claims of best sensor, sharpest image, least noise, etc, etc. Gizmodo goes back for round two and puts the Drift Ghost, Sony Action Cam, Contour+2, and GoPro 3 through the paces in their various modes and configurations. The good news (if you already bought one) is that they’re all pretty good.
