Focus lock photography

When the subject to be focused is outside the autofocus frame in the center of the picture, use focus lock, which enables you to change the picture composition while locking the focus.

1. Compose the picture.

If the shutter is released in a condition like that in the above example where the main subject is outside the autofocus frame, the background is in focus, and the main subject is out of focus. In such situations, use focus lock to change the picture composition while temporarily locking the focus on the main subject.

2. Center the autofocus frame on the main subject and lightly press the Shutter Release button.

The green LED lights up when correct focus has been achieved, and the focus is locked as long as the Shutter Release button is depressed lightly.

Do not change the camera-to-subject distance

While the green LED lights up, the focus is locked. Do not change the camera-to-subject distance.
