There is an
AF/MF | AEL switch on my Sony α7R II. If I switch this to
AF/MF, and then press the button inside the switch, nothing happens on the viewfinder screen or back panel screen.
How do I turn on manual focus for a Sony α7R II?
You can easily switch the focusing mode from auto to manual and vice versa while shooting without changing your holding position.
Switch the AF/MF/AEL switch lever to the AF/MF position, then press the AF/MF button.
During auto focus: Temporarily switches the focusing mode to manual. Adjust the focus while the AF/MF button is being held down.
During manual focus: Temporarily switches the focusing mode to auto while the AF/MF button is held down, and locks the focus.
Hint: If you select [AF/MF Ctrl Toggle] in [AF/MF Button] under [Custom Key Settings], the focusing mode remains switched even if you remove your finger from the button.
