B
Autofocus
The camera may not focus as expected in the following situations. In some rare cases, the subject
may not be in focus despite the fact that the focus area or the focus indicator glows green:
• Subject is very dark
• Objects of sharply differing brightness are included in the scene (e.g. the sun behind the subject
makes that subject appear very dark)
• No contrast between the subject and surroundings (e.g. a portrait subject, wearing a white shirt, is
standing in front of a white wall)
• Several objects are at different distances from the camera (e.g. the subject is inside a cage)
• Subjects with repeating patterns (window blinds, buildings with multiple rows of similarly shaped
windows, etc.)
• Subject is moving rapidly
In the situations noted above, try pressing the shutter-release button halfway to refocus several
times, or select auto mode and use focus lock (A 66) to take the picture by first focusing on an
object that is the same distance from the camera as the desired subject.

Notes About Face Detection
See "Using Face Detection" (A 65) for more information.
C
AF-assist Illuminator and Flash
If the subject is dimly lit, the AF-assist illuminator (A 88) may light when the shutter-release button
is pressed halfway, and the flash (A 51) may fire when the shutter-release button is pressed all the
way down.
C
To Make Sure You Do Not Miss a Shot
If you are concerned that you might miss a shot, press the shutter-release button all the way without
first pressing it halfway.
