When [Face Detection AF] is [Face Det. & Tracking] When clicking on a person's face, a tracking frame appears on the face, and the tracking will be in progress. Tracking Frame If something other than the face of a person is clicked, depending on the AF frame size, the operation differs as follows. When [AF Frame Size] is set to [Auto], the tracking frame appears on the subject clicked on the screen and is tracked. If [AF Frame Size] is set to [Big] or [Small], and [Touch Operation] is set to [Normal], when there is no person's face, the AF frame appears where it was clicked. If there is a person's face in the screen, the face frame remains displayed. When [AF Frame Size] is set to [Big] or [Small] and [Touch Operation] is set to [Select Tracked Object], a tracking frame is displayed on the subject clicked on the screen and is tracked. Note When the tracking frame is displayed, the face frame will not be displayed. When [Face Only] is selected for [Face Detection AF] Clicking a person's face is the same as in [Face Det. & Tracking] in the previous section. If something other than a person's face is clicked, the focus does not change.  Autofocus • The focus position for autofocus varies slightly depending on the shooting conditions such as the subject, brightness, and zoom position.
