Touching your camera to re-focus its lens while filming your next budget masterpiece isn't necessarily a good idea, and lugging a laptop around to handle the task remotely isn't exactly practical for today's modern gorilla filmmaker. The $400 USB Follow Focus looks to be a much more simple solution. It's quite simply a knob in an aluminum enclosure that connects over mini-USB. Plug it in and welcome to your next Oscar -- or Emmy, anyway. There are a suite of buttons that can be used to define focal presets and it has compatibility with most Canon HD DSLR
shooters. The results? Check the two videos after the break and see for yourself.
