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 (

0 113), 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 (

0 103).

Position the subject in the 
selected focus point and

shutter-release button pressed 
halfway (q), press the center of the 
sub-selector (w) to lock both focus 
and exposure (an AE-L icon will be 
displayed in the viewfinder). Focus 
will remain locked while the center 
of the sub-selector is pressed, even 
if you later remove your finger from 
the shutter-release button.
