Step 3 Focus and Shoot
Basic Photography and Playback: Easy Auto Mode
B Face Priority
If no face is recognized when the shutter-release button is pressed halfway, the camera focuses on
the center of the frame.
The camera may be unable to detect faces in the following situations:
- When faces are partially hidden by sunglasses or other obstructions
- When the subject is not looking directly at the camera
- When faces take up too much or too little of the frame
The camera’s ability to detect faces depends on a variety of factors, including whether or not the
subject is facing the camera.
It is very rare cases, but if you shoot a subject with which autofocus may not perform as expected,
the subject may not be in focus despite the fact that the double border glows green. When the
camera is unable to focus, refocus on another subject positioned at the same distance from the
camera as the actual portrait subject, and use focus lock (A31).
B Autofocus
Autofocus may not perform as expected in the following situations. In some rare cases, the subject
may not be in focus despite the fact that the active 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 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 several
times, or focus on another subject and use focus lock. When using focus lock, be sure that the
distance between the camera and the subject with which focus was locked is the same as that for
the actual subject.
D AF-assist Illuminator and Flash
If the subject is poorly lit, the AF-assist illuminator may light by pressing the shutter-release button
halfway, or the flash may fire by pressing the shutter-release button all the way down. The
illuminator has a range of about 2.4 m (7 ft. 10.5 in.) at the maximum wide-angle position and 1.7 m
(5 ft. 6.9 in.) at the maximum telescopic position. The AF-assist illuminator can be set to Off manually
(A83), although in this case the camera may not focus when lighting is poor.
