Movie Shooting Cautions
White <s> and Red <E> Internal Temperature Warning Icons
If the camera’s internal temperature increases due to prolonged movie
shooting or under a high ambient temperature, a white icon will
appear. Even if you shoot a movie while this icon is displayed, the
movie’s image quality will hardly be affected. However, if you shoot still
photos, the image quality of the still photos may deteriorate. It is
recommended to stop still photo shooting for a while and allow the
camera to cool down.
If the camera’s internal temperature further increases while the white
icon is displayed, a red icon will start blinking. This blinking
icon indicates that movie shooting will soon stop automatically. If this
happens, you will not be able to shoot again until the camera’s internal
temperature decreases. Turn off the power and let the camera rest for a
while.
Shooting a movie at a high temperature for a prolonged period will cause
the and icons to appear earlier. When you are not shooting,
turn off the camera.
Recording
If the attached lens has an Image Stabilizer and you set the Image
Stabilizer (IS) switch to <1>, the Image Stabilizer will operate at all
times even if you do not press the shutter button halfway. The Image
Stabilizer consumes battery power and may shorten the total movie
shooting time or decrease the number of possible shots. If you use a
tripod or if the Image Stabilizer is not necessary, it is recommended to set
the IS switch to <2>.
The camera’s built-in microphone will also pick up camera operation
noise. Using a commercially-available external microphone can prevent
(or reduce) these noises from being recorded.
Do not connect anything other than an external microphone to the
camera’s external microphone IN terminal.
If the brightness changes during autoexposure movie shooting, that part
may look momentarily still when you play back the movie. In such cases,
shoot movies with manual exposure.
