Notes on Movie Shooting
During movie shooting, do not point the lens toward the sun. The sun's
heat can damage the camera's internal components.
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.
You cannot magnify the image during movie shooting.
Be careful not to cover he microphone (p.182) with your finger, etc.
Cautions for movie shooting are on pages 212 and 213.
If necessary, also read the Live View shooting cautions on pages
178 and 179.
Movie-related settings are under the [Z1] and [Z2] tabs (p.207).
A movie file is recorded each time you shoot a movie. If the file size
exceeds 4 GB, a new file will be created for every subsequent 4 GB.
The movie image's field of view is approx. 100% (with movie recording
size set to [A]).
Monaural sound is recorded by the camera's built-in microphone (p.182).
Most commercially-available external stereo microphones with a 3.5 mm
diameter mini plug can be connected to the camera.
You can use Remote Controller RC-6 (sold separately, p.309) to start
and stop the movie shooting if Drive/self-timer is <Q>. Set the shooting
timing switch to <2> (2-sec. delay), then press the transmit button. If the
switch is set to <o> (immediate shooting), still photo shooting will take
effect.
With a fully-charged Battery Pack LP-E12, the total movie shooting time
will be as follows: approx. 1 hr. 5 min. at room temperature (23°C/73°F),
and approx. 1 hr. at low temperatures (0°C/32°F).
The focus preset function is possible for movie shoo ing when using a
(super) telephoto lens equipped wi h the focus preset mode, available
since the second half of 2011.
