Using Autofocus in 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
