Greetings,
You need to have Continuous AF enabled in Cinema OS. Be sure to install FW version 1.0.7.1 or 1.0.8.1. This way you also get Large Focus Guide, Standard / Thick AF box, Gridlines on playback and support for reset AF point to center using Set or Joystick if progrmmed. Also*** you can map ISO or shutter speed to the quick control dial on the back... I use shutter angle and recommend that unless you have a specific reason not to 😉
