Choose the focus point.
Wide and normal area autofocus
: Rotate the focus 
selector lock to “
J” and use the multi selector to 
move the focus point to any point in the frame. 
Return the focus selector lock to “L” when 
selection is complete.
Face-priority autofocus
: A double yellow border will 
be displayed when the camera detects a portrait 
subject facing the camera (if multiple faces, up 
to a maximum of five, are detected, the camera 
will focus on the closest subject).
Manual focus
: Use the multi selector to choose the 
focus point for electronic rangefinding (pg. 59) 
as described for wide and normal area 
autofocus, above.

Focus.
Autofocus
: In wide and normal area autofocus, the 
camera will focus while the shutter-release 
button is pressed halfway. In face-priority 
autofocus
, the camera sets focus for the face in 
the double yellow border while the shutter-
release button is pressed halfway; if the camera 
can no longer detect the subject (because, for 
example, the subject has looked away), borders 
will no longer be displayed. The focus point will 
blink green and the monitor may brighten or 
darken while the camera focuses. If the camera 
is able to focus, the focus point will be displayed in green; if the camera is 
unable to focus, the focus point will blink red. Note that pictures can be taken 
even when the focus point blinks red, and that single-servo autofocus is used 
regardless of the option selected for autofocus mode (pg. 54). Check focus in 
the monitor before shooting.
