~ Using Autofocus in Live View
Autofocus is slower in live view and the monitor may brighten or darken while the camera
focuses. The camera may be unable
to focus in the following situations:
• 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
Note that the focus point may sometimes be displayed in green when the camera is unable
to focus.
