Using Autofocus in Live View Photography and Movie Live View
Use an AF-S lens. The desired results may not be achieved with other
lenses or teleconverters. Note that in live view, autofocus is slower and
the monitor may brighten or darken while the camera focuses. The
focus point may sometimes be displayed in green when the camera is
unable to focus. 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 includes spot lighting or 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
