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 11).
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, A, and
% modes,
exposure can be adjusted by ±5 EV in increments of 1 /
3
EV. Note that the effects of values
over +3 EV or under –3 EV can not be previewed in the monitor.

Using Autofocus in Live View
Autofocus is slower in live view and the monitor may brighten or darken while the camera
focuses. 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 the
subject is lit by spot lighting or by 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
Note that the focus point may sometimes be displayed in green when the camera is unable
to focus.
