I recently picked up a JVC GY-HM700 and am having an issue with the camera focusing while on full auto. It focuses fine manually. Everything else appears to work on full auto other than the camera's lens not focusing.
JH is right. No autofocus on any pro cam that I have seen unless it's a pro handheld with fixed lenses. I have seen folks confused by the slider switch in front of the rocker zoom switch. This is to set the iris on manuel or auto. Easy to be confused by this if you are new to these cams.
