I turn on my camera and my default is that all (main) camera settings are displayed and 39 times out of 40 this is the case.
I have it set - when I press the back most right upper button - the AF point selection appears on my screen. Then I press 'SET' and it selects the center AF point, for example.
EDIT: not certain what you mean by AF button - do you mean the AF-ON button?
when I press that button - I have the "main" camera settings already displayed - but pressing it activates the metering scale





. Been using them for video without issue.
