The Drift Ghost offers filmmakers options that you just can't find on other models. For instance, for high-quality audio, the HD Ghost's 3.5mm microphone input is a welcome option. A rotating lens helps you mount it at offbeat angles, while still keeping the horizon level. It's also waterproof to almost 9 feet below without the need for external housing. Reviewing your footage is easy, thanks to the 2-inch display, and there are apps for iOS and Android phones, too, if you want to set the camera up from a distance (though it comes bundled with a remote).
