Notes on Movie Shooting
The camera cannot autofocus continuously like a camcorder.
If you use AF during movie shooting, the focus may become greatly
blurred momentarily and the exposure may change.
If you use a USM lens and perform AF while shooting a movie in low
light, horizontal noise stripes may be recorded. With certain lenses
having an electronic focusing ring, horizontal noise stripes may be
recorded even when you focus manually (MF).
Zooming the lens during movie shooting is not recommended. Zooming
the lens can cause changes in the exposure regardless of whether the
lens’ maximum aperture changes or not. Exposure changes may be
recorded as a result.
During movie shooting, do not point the lens toward the sun. The sun’s
heat can damage the camera’s internal components.
Under [51: Record func+card/folder sel.], even if [Record func.] is set
to [Rec. to multiple] (zp.118), the movie cannot be recorded to both
Card 1 <f> and Card 2 <g>. If [Rec. separately] or [Rec. to
multiple] is set, the movie will be recorded to the card which is set for
[Playback].
If <Q> is set and the ISO speed or aperture changes during movie
shooting, the white balance may also change.
If you shoot a movie under fluorescent or LED lighting, the movie may
flicker.
When you shoot at high ISO speeds, color tone may be changed
depending on the movie-recording size settings.
When you press the <u> button, the “x5” or “x10” figure displayed on
the screen’s bottom right indicates the magnification based on 35mm
full-frame sensor size.
Cautions for movie shooting are on pages 55 and 56.
If necessary, also see “Live View Shooting Cautions” on pages 221
and 222 in the EOS-1D X Instruction Manual.
