Autofocus may not perform as expected in the following situations:

•Subject is very dark

•Objects of sharply differing brightness are included in the scene (e.g., the sun is behind the subject and is in deep shadow)

•No contrast between the subject and surroundings (e.g., when the subject is standing in front of a white wall, wearing a white shirt)

•Several objects are at different distances from the camera (e.g., the subject is inside a cage)

•Subject is moving rapidly

In the situations noted above, try pressing the shutter-release button halfway to refocus sev- eral times, or use focus lock below.
