Recording Movies

Banding or distortion may be visible in the monitor and in the final movie 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. Jagged edges, false colors, moiré, and bright spots may also appear. When recording
movies, 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.

Recording ends automatically if the lens is removed.

Live view can be used to record movies for up to an hour. Note,
however, that when used in live view mode for extended periods, the
temperature of the camera’s internal circuits may rise, resulting in
image noise and unusual colors (the camera may also become
noticeably warm, but this does not indicated a malfunction). To
prevent damage to the camera’s internal circuits, recording will end
automatically before the camera overheats. A count-down display will
appear in the monitor 30 s before shooting ends. At high ambient temperatures, this display
may appear immediately when live view mode is selected.

Autofocus is not available when recording movies. Matrix metering is used regardless of the
metering method selected.
