I am getting worried now. When any AF lens is attached and AF is on, the camera doesn't take a shot no matter how long I press the shutter release button for. AF lenses in manual mode or Manual lenses – no problem, it focuses and takes a shot nicely. Green dot doesn't come up at all. What really worries me is that it refuses to autofocus in LiveView mode. When I touch the shutter release button, it switches off LiveView.
