Sony ILCA-99M2 - Manual (Page 69)

AF/MF control
You can easily switch the focusing mode from auto to manual and vice versa while shooting
without changing your holding position.
During auto focus:
Temporarily switches the focusing mode to manual. Adjust the focus by turning the focus ring
(A) while holding down the AF/MF button. For SAM lenses other than SAL18135 (as of the day
this camera was released), the focusing ring cannot be rotated.
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(Shoot.)], the focusing mode
remains switched even if you remove your finger from the button.
