Take the picture.
Press the shutter-release button the rest of the way
down to take the picture. If continuous high speed
or continuous low speed is selected for Release mode, the
monitor will turn off while the shutter-release button is
pressed. The frame advance rate for continuous mode is the
same as that selected for standard shooting.
~ Contrast-Detect Autofocus
The camera will not continue to adjust focus while the AF-ON button 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.
~ Focusing 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
• 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., windows
in a skyscraper)
• The subject is moving
