can be used to change the composition after focusing on the
subject in the center of the frame, allowing you to focus on a
subject that will not be in the center of the final composition. If
the camera is unable to focus using autofocus (

also focus on another subject at the same distance and then use
focus lock to recompose the photograph. Focus lock is most
effective when an option other than

is selected for
