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 AF/access lamp lights in 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., an animal inside a cage)
• Subjects that repeat the same pattern (e.g., as window blinds or buildings lined with windows of
the same shape)
• Subject is moving rapidly
In these situations, 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.
The camera can also be focused using manual focus (
E2).
B
The Subject Is Too Close to the Camera
If the camera does not focus, try shooting with p (macro close-up) (A68) in the focus mode, or
Close-up ( A42) scene mode.
C
AF-assist Illuminator
In dark places, the AF-assist illuminator ( A105) may light when the shutter-release button is
pressed halfway.
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.
C
Focus Lock
Use focus lock to focus on off-center subjects when center is selected for AF area mode.
• Be sure that the distance between the camera and the subject does not change.
• When the shutter-release button is pressed halfway, the exposure is locked.
Instead of pressing the shutter-release button halfway, you can also press the g (AE-L/AF-L) button
to shoot with focus lock ( A107) (except for Scene auto selector (A40) in scene mode).
