I am trying to set up continuous autofocus without pressing the shutter, and can only get it to work on one of my 4 sony A6000's. For the life of me I cannot figure out what is different about the settings on that one camera that will enable the lens to refocus without pressing down the shutter when I move the camera around to different subjects. I have tried different lenses, and they all will continuously autofocus on just that one camera. All of the sony a6000's have been upgraded to version 3.2. Thanks for any ideas/help.
