Using Autofocus in Live View
Use an AF-S or AF-P 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

Focus-Point Selection
Except in subject-tracking AF, pressing J during focus-point selection
selects the center focus point. In subject-tracking AF, pressing J starts
subject tracking instead. Manual focus-point selection is not available
in auto-area AF.
