General Movie Recording Precautions
Caution
Precautions for movie recording
Do not point the camera toward an intense light source, such as the sun or an
intense artificial light source. Doing so may damage the image sensor or the
camera’s internal components.
If you record something that has fine detail, moire or false colors may result.
White balance may change if the ISO speed or aperture value changes during
movie recording when [ ] or [ ] is set.
Recording movies under fluorescent or LED lighting may cause the screen to
flicker.
Autofocusing with a USM lens during movie recording under low light may cause
horizontal banding to be recorded in movies. The same type of noise may occur if
you focus manually ( ) with certain lenses equipped with an electronic focusing
ring.
Recording a few test movies is recommended if you intend to perform zooming
during movie recording. Zooming as you record movies may cause exposure
changes or lens sounds to be recorded, an uneven audio level, or loss of focus.
Large aperture values may delay or prevent accurate focusing.
Performing AF by pressing the shutter button halfway during movie recording may
cause the following kinds of issues: significant temporary loss of focus, recording of
changes in movie brightness, temporary stopping of movie recording, or recording
of mechanical lens sounds.
Avoid covering the built-in microphones ( ) with your fingers or other objects.

The camera may become hot in movie recording while connected via Wi-Fi. Use a
tripod or take other measures to avoid handheld recording.
Red [ ] internal temperature warning icon
If the camera’s internal temperature increases due to prolonged movie recording or
under a high ambient temperature, a red [ ] icon will appear.
The red [ ] icon indicates that movie recording will soon end automatically. If this
happens, you will not be able to record again until the camera’s internal
temperature decreases, so turn off the power and let the camera cool down a
while. Note that the time until movie recording stops automatically when the red
[ ] icon is displayed varies depending on shooting conditions.
Recording a movie at a high temperature for a prolonged period will cause the red
[ ] icon to appear earlier. When you are not recording, always turn off the camera.
