The autofocus system

As you press the shutter button, your camera sends

sound waves - within 10 thousandths of a second - to the

central part of the scene (approximate area circled in

white, see illustration).

The sound waves are used to measure the distance to

the person or object (in the central part of the scene) that

is

closest to the camera.

A built-in computer then uses this measurement to pro-

vide the correct lens setting, so

be sure that:

The sound waves must have a clear path to your subject.

If

an object (candlestick, centerpiece, etc.1 prevents the

sound waves from reaching your subject, the lens will

focus on that object, and your subject will not be clear

and in focus.

When photographing more than one person,

place

everyone the same distance from the camera.

When taking a picture through glass, turn off the auto-

focus system.
