Live View Shooting Cautions
Image Quality
When you shoot at high ISO speeds, noise (such as dots of light and
banding) may become noticeable.
Shooting in high temperatures may cause noise and irregular colors in
the image.
If Live View shooting is used continuously for a long period, the camera’s
internal temperature may rise, and image quality may deteriorate. Stop
Live View shooting when not shooting images.
If you shoot a long exposure while the camera’s internal temperature is
high, image quality may deteriorate. Stop Live View shooting and wait a
few minutes before shooting again.
White <s> and Red <E> Internal Temperature Warning
If the camera’s internal temperature increases due to prolonged Live
View shooting or under a high ambient temperature, a white icon
will appear. If you continue shooting while this icon is displayed, the
image quality of still photos may deteriorate. It is recommended to
temporarily exit Live View shooting and allow the camera to cool down
before shooting again.
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 the Live View 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.
Using Live View shooting 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.
If the camera’s internal temperature is high, the image quality of high ISO
speed images or long exposures may be degraded even before the white
icon is displayed.
