A Chinese company called Cinematics has released a focus controller for the Canon cameras. Mainly for video production, it looks pretty cool.

It controls allows you to manually focus an autofocus Canon EF lens by using the lenses own built in focus motor. To do this it communicates with the camera using Canon’s own USB protocols which are normally used when the camera is communicating with Canon’s EOS Utility software on a computer.
