Nikon 25215 manual Focus Lock, Continuous-servo AF

Taking Photographs—Focus

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 area in the final composition. It can also be used when the autofocus system is unable to focus ( 82).

In single-servo AF, focus locks automatically when the in-focus indicator (●) appears in the viewfinder. In continuous-servo AF, focus must be locked manually using the AE-L/AF-Lbutton. To recompose a photograph using focus lock:

1 Position the subject in the selected focus area and press the shutter-re- lease button halfway to initiate focus.

2 Check that the in-focus indicator (●) appears in the viewfinder. Single-servo AF

Focus will lock automatically when the in- focus indicator appears, and remain locked until you remove your finger from the shutter- release button. Focus can also be locked by pressing the AE-L/AF-Lbutton (see below).

Continuous-servo AF

Press the AE-L/AF-Lbutton to lock both focus and exposure. Focus will remain locked while the AE-L/AF-Lbutton is pressed, even if you later remove your finger from the shutter-re- lease button.
