785 Problems and Solutions
Photos are out of focus:
• Is the camera in manual focus mode? To enable autofocus, select AF-S ,
AF-C , or AF-F for focus mode.
• The camera may be unable to focus if:
- 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,
- the focus point includes night-time 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, or
- the subject is dominated by regular geometric patterns (e.g., blinds
or a row of windows in a skyscraper).
• In focus mode AF-C , the focus point may flash while the shutter-
release button is pressed halfway or the AF-ON button is pressed,
indicating that the camera is no longer able to focus. The focus
operation can be resumed by releasing and then pressing the button
again.
