Focus Lock
In A-REC mode, the camera automatically focuses on the sub-
ject at the center of the frame. If your subject is not located at
the center of the frame when the shutter-release button is
pressed halfway, the camera will focus on the background. Fo-
cus lock allows you to first focus on your subject, then adjust
the composition before taking the photograph.
1 Focus the camera
Position the subject in the center focus area (shown by the
focus target in the viewfinder) and press the shutter-re-
lease button halfway.
2 Check the AF lamp
With the shutter-release button held halfway down, check
that the green AF lamp next to the viewfinder glows steadily.
3 Recompose the photograph and shoot
Focus will remain locked as long as the shutter-release but-
ton is held halfway. Keeping the shutter-release button held
halfway down, recompose your photograph. Press the shut-
ter-release button the rest of the way down to shoot.

Do not change the distance between the camera and the sub-
ject while focus lock is in effect. If your subject moves, remove
your finger from the shutter-release button and focus again at
the new distance.
In M-REC mode, you can also use focus area selection to focus on an off-
center subject. See:
