Focus Lock
Focus lock can be used to change the composition after focusing,
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 (
113), 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 auto-area AF is selected for AF-area
mode (
104).
