During Recording

While pictures are being recorded, the number of exposures remaining display will blink. Do not
open the battery-chamber/memory card slot cover while pictures are being recorded. Cutting
power or removing the memory card in these circumstances could result in loss of data or in damage
to the camera or card.

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 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., an animal 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.

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, exposure is locked.

AF-assist illuminator

If the subject is poorly lit, the AF-assist illuminator (

A163) may light by pressing the shutter-release

button halfway.
