Notes on Movie Shooting
The camera cannot autofocus continuously like a camcorder.
Autofocusing during movie shooting may momentarily throw the focus far
off or change the exposure.
When you autofocus during movie shooting under low-light conditions
using a USM lens, horizontal stripes (noise) may be recorded. Note that
with certain lenses equipped with the electronic focusing ring, similar
noise may be recorded even with manual focusing (MF).
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] (p.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.
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.
Cautions for movie shooting are on pages 247 and 248.
If necessary, also read the Live View shooting cautions on pages
221 and 222.
Movie-related settings are under the [z4] and [z5] tabs (p.245).
A movie file is recorded each time you shoot a movie. If the file size
exceeds 4 GB, a new file will be created.
The movie image’s field of view is approx. 100% (with movie recording
size set to [A]).
You can also focus the image by pressing the <p> button.
To focus during movie shooting, press the <p> button. You cannot
focus by pressing the shutter button.
