Focus Lock
Focus lock can be used to focus on a subject not in any of the five focus areas,
or on other occasions when you would otherwise be unable to focus on the
subject using autofocus.
The procedure for using focus lock differs depending on whether you are using-
single or continuous servo AF. Follow the steps below.
1
Position the subject in the focus area (A) and press the shutter-release
button half way (B).

In single servo AF, confirm that the in-focus indicator (
●
) appears in the
viewfinder. Focus will remain locked at the current setting as long as the
shutter-release button is held half way down. To lock exposure as well as
focus, press the
button. Focus and exposure will remain locked as long
as the
button is held down, even if you remove your finger from the
shutter-release button.
Camera Settings: Focus Lock
The
button can be set to lock only focus, rather than both focus and exposure.
