Shooting in Live View Mode
To prevent light entering via the viewfinder from interfering with exposure, remove the
rubber eyecup and cover the viewfinder with the supplied DK-5 eyepiece cap before
shooting (0 38).
Although they will not appear in the final picture, flicker, banding, or distortion may be
visible in the monitor under fluorescent, mercury vapor, or sodium lamps or if the camera is
panned horizontally or an object moves at high speed through frame. Bright light sources
may leave after-images when the camera is panned. Bright spots may also appear. When
shooting in live view mode, avoid pointing the camera at the sun or other strong light
sources. Failure to observe this precaution could result in damage to the camera's internal
circuitry.
Live view ends automatically if the lens is removed or when the monitor is closed (closing
the monitor does not end live view on televisions or other external displays).
Live view may end automatically to prevent damage to the camera's internal circuits; exit live
view when the camera is not in use. Note that the temperature of the camera's internal
circuits may rise and noise (bright spots, randomly-spaced bright pixels, or fog) may be
displayed in the following instances (the camera may also become noticeably warm, but this
does not indicate a malfunction):
• The ambient temperature is high
• The camera has been used for extended periods in live view or to record movies
• The camera has been used in continuous release mode for extended periods
If a warning is displayed when you attempt to start live view, wait for the internal circuits to
cool and then try again.

The Count Down Display
A count down will be displayed 30 s before live view ends automatically (0 103; the timer
turns red 5 s before the auto off timer expires or if live view is about to end to protect the
internal circuits). Depending on shooting conditions, the timer may appear immediately
when live view is selected. Note that although the count down does not appear in the
information display or during playback, live view will still end automatically when the timer
expires.
