Step 3 Focus and Shoot

BDuring Recording

While pictures are being recorded, the O (wait) icon will be displayed, the Cor X(when a memory card is inserted in the camera) icon blinks, and the AF lamp blinks. Do not turn the camera off, open the battery-chamber/memory card slot cover, or remove or disconnect the power source while these icons are displayed. Cutting power or removing the memory card in these circumstances could result in loss of data or in damage to the camera or card.

CAutofocus

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 AF lamp 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.

DFocus Lock

To focus on an off-center subject when [Center] is selected for [AF area mode], use focus lock as described blow.

•Be sure that the distance between the camera and the subject does not change while focus is locked.

•When the shutter-release button is pressed halfway, exposure is locked.

DAF-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 1.9 m (6.2 ft.) at the maximum wide-angle position and about 1.1 m (3.6 ft.) at the maximum telescopic position. The AF-assist illuminator can be set to [Off] manually (A129), although in this case the camera may not focus when lighting is poor.
