DContrast-Detect Autofocus

The camera will not continue to adjust focus while the Bbutton is pressed in continuous-servo autofocus mode. In both single-servo and continuous-servo autofocus modes, the shutter can be released even when the camera is not in focus.

DFocusing with Contrast-Detect Autofocus

Contrast-detect autofocus will take longer than normal (phase-detection) autofocus. In the following situations, the camera may be unable to focus using contrast-detect autofocus:

•The camera is not mounted on a tripod

•The subject contains lines parallel to the long edge of the frame

•The subject lacks contrast

•The subject in the focus point contains areas of sharply contrasting brightness, or the subject is lit by spot lighting or by a neon sign or other light source that changes in brightness

•Flicker or banding appears under fluorescent, mercury-vapor, sodium- vapor, or similar lighting

•A cross (star) filter or other special filter is used

•The subject appears smaller than the focus point

•The subject is dominated by regular geometric patterns (e.g., blinds or a row of windows in a skyscraper)

•The subject is moving
