camera's focus mode to [MF], and focus by
turning the focusing ring (focusing/control ring).
When the AF does not operate after switching
z
the focus mode from [MF] to [AF] and when the
focus mode is not displayed on the camera's
menu, turn the focus ring in the direction of
[Infinity] until the focusing position is within the
