Troubleshooting Guide
If you use flash, the shutter will make two sounds each time you shoot
(p.202).
It indicates that the camera’s internal temperature is high. If the white
<
> icon displayed, the still photo’s image quality may deteriorate. If
the red <E> icon is displayed, it indicates that the Live View or movie
shooting will soon stop automatically (p.217, 243).
If the card’s writing speed is slow, movie shooting may stop
automatically. With IPB compression, use a card with an actual
reading/writing speed of at least 10 MB/sec. With ALL-I (I-only)
compression, the card should have an actual reading/writing speed of
at least 30 MB/sec. To find out the card’s speed, see the card
manufacturer’s Web site (p.219).
If the movie shooting time reaches 29 min. 59 sec., the movie shooting
will stop automatically.
If the shooting mode is <d/s/f/BULB>, the ISO speed will be set
automatically. In the <a> mode, you can freely set the ISO speed
(p.226).
Under [z2: ISO speed settings], if [ISO speed range]’s [Maximum]
is set to [51200/H] or higher, the manual setting range’s Maximum will
be expanded to enable ISO 32000/40000/51200 to be set. However,
since movie shooting at ISO 32000/40000/51200 may result in
substantial noise, the expanded ISO speed (“H” displayed) will be
used.
The shutter makes two shooting sounds during Live View shooting.
During Live View and movie shooting, a white or red E
icon is displayed.
Movie shooting stops by itself.
The ISO speed cannot be set for movie shooting.
