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 and the focus indicator glow 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
Focus Lock
To focus on off-center subject, use focus lock as described blow.
• Be sure that the distance between the camera and the subject does not change while focus is
locked.

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 (
A 87), although in this case the camera may not focus when lighting is poor.
