Focusing on Subject

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.

selector (A36) in scene mode).

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 focus area or focus
indicator 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 with repeating patterns (window blinds, buildings with multiple rows
of similarly shaped windows, etc.)
• 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 focus using manual focus (
