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 |
| 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. |
