Using the Focus Lock

The following types of subject may not be suited to autofocus photography. Use the focus lock in these situations.

¡Subjects with extremely low contrast to the surroundings

¡Subjects with extremely bright objects at the center of the composition

¡Subjects that are moving quickly

¡Subjects through glass

Try to shoot as close to the glass as possible to reduce the chances of light reflecting back off the glass.

and wait until the camera beeps twice. Without releasing your finger, re-aim the camera to compose the shot as desired and press the shutter button all the way.
