A
Flicker
You may notice flicker or banding in the monitor during live view or when shooting movies
under certain types of lighting, such as fluorescent or mercury-vapor lamps. Flicker and
banding can be reduced by choosing a
Flicker reduction option that matches the
frequency of the local AC power supply (
0
139).
A
Exposure
Depending on the scene, exposure may differ from that which would be obtained when live
view is not used. Metering in live view is adjusted to suit the live view display, producing
photographs with exposure close to what is seen in the monitor. In
P
,
S
, and
A
modes,
exposure can be adjusted by ±5 EV in increments of
1
/
3
EV (
0
81). Note that the effects of
values over +3 EV or under –3 EV can not be previewed in the monitor.
A
HDMI
When the camera is attached to an HDMI video device, the
camera monitor will turn off and the video device will display
the view through the lens as shown at right. Movies can not be
recorded and photographs can not be taken in live view while
the camera is connected to an HDMI-CEC device.
D
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
54).
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 in the monitor when the camera is panned. 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.
Live view may end automatically to prevent damage to the camera’s internal circuits; exit live
view when the camera is not 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
37; 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.
