In live view, the focus area for autofocus is shown in the monitor. Using the multi
selector to reposition focus area shifts focus to another part of the frame. What
controls how the focus point is selected is AF-area mode.
Live view offers
a choice of AF-area modes, including wide- and normal-area
AF, subject tracking, and face priority.
AF-area mode selection is also available when the camera is used to record
movies.
