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 prolonged period, the camera's internal temperature may rise, and image quality may deteriorate. Always exit Live View shooting when you are not shooting. If you shoot a long exposure while the camera's internal temperature is high, image quality may deteriorate. Exit Live View shooting and wait a few minutes before shooting again. White and Red Internal Temperature Warning Icons If the camera's internal temperature increases due to prolonged Live View shooting or under a high ambient temperature, a white or red icon will appear. The white icon indicates that the image quality of still photos will deteriorate. You should exit Live View shooting and allow the camera's internal temperature to cool before shooting again. The red 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. Exit the Live View shooting or 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 or icon 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 deteriorate even before the white icon is displayed. Shooting Result If you take the picture in magnified view, the exposure may not come out as desired. Return to the normal view before taking the picture. In magnified view, the shutter speed and aperture will be displayed in orange. Even if you take the picture in magnified view, the image will be captured in the normal view range. If [z3: Auto Lighting Optimizer] (p.140) is set to other than [Disable], the image may look bright even if a decreased exposure compensation or decreased flash exposure compensation is set. 249

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 prolonged period, the
camera’s internal temperature may rise, and image quality may
deteriorate. Always exit Live View shooting when you are not shooting.
If you shoot a long exposure while the camera’s internal temperature is
high, image quality may deteriorate. Exit Live View shooting and wait a
few minutes before shooting again.
White <
s
> and Red <
E
> Internal Temperature Warning Icons
If the camera’s internal temperature increases due to prolonged Live
View shooting or under a high ambient temperature, a white <
s
> or red
<
E
> icon will appear.
The white <
s
> icon indicates that the image quality of still photos will
deteriorate. You should exit Live View shooting and allow the camera’s
internal temperature to cool before shooting again.
The red <
E
> 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. Exit the Live View shooting or
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 <
s
> or <
E
> icon 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 deteriorate even before the white
<
s
> icon is displayed.
Shooting Result
If you take the picture in magnified view, the exposure may not come out
as desired. Return to the normal view before taking the picture. In
magnified view, the shutter speed and aperture will be displayed in
orange. Even if you take the picture in magnified view, the image will be
captured in the normal view range.
If [
z
3: Auto Lighting Optimizer
] (p.140) is set to other than [
Disable
],
the image may look bright even if a decreased exposure compensation
or decreased flash exposure compensation is set.
