distribution graph in the top right of the screen,
enabling the focus to be aligned more easily,
and therefore particularly useful when using
manual focus. The screen display that appears
after pressing the FOCUS ASSIST button can be
changed with the FOCUS ASSIST setting in the
settings menu SW MODE screen. (Page 89)
