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 a high ambient temperature, a white icon <s> 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 degrade. You should stop shooting
still photos for a while and allow the camera to cool down.
If the camera’s internal temperature further increases while the white
icon <s> is displayed, a red icon <E> may start blinking. This blinking
icon is a warning 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 <s> and <E> icons to appear earlier. When you are not shooting,
turn off the camera.
Recording and Image Quality
If the attached lens has an Image Stabilizer, 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, you should 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 there is a very bright light source in the picture, the bright area may
appear black on the LCD monitor. In movies, the bright areas will be
recorded in almost the same way you see it on the LCD monitor.
In low light, noise or irregular colors may appear in the image. In movies,
the bright areas will be recorded in almost the same way you see it on
the LCD monitor.
