compose photographs with the main subject almost anywhere in the frame.

Focus Lock
Focus lock can be used to change the composition after focusing in AF-A, AF-S, and AF-C
focus modes (
0 51), making it possible to focus on a subject that will not be in a
focus point in the final composition. If the camera is unable to focus using autofocus
(
0 52), focus lock can also be used to recompose the photograph after focusing on
another object at the same distance as your original subject. Focus lock is most
effective when an option other than
e (Auto-area AF) is selected for AF-area mode
( 0 53).
