Troubleshooting Guide
Make sure the external flash (or PC sync cord) is securely attached to
the camera.
If you use a non-Canon flash with Live View shooting, set the [z
Silent shoot.] menu to [Disable] (p.141).
The built-in flash’s pop-up mechanism moves slightly. This is normal.
If you use flash, the shutter will make two sounds each time you shoot
(p.137).
For Live View shooting, use a memory card (a hard disk-type card is
not recommended). A hard disk-type card requires a lower
temperature range for operation than normal memory cards. If the
temperature gets too high, the Live View shooting may stop
temporarily to prevent damage to the card’s hard disk. When the
camera’s internal temperature decreases, you can resume Live View
shooting (p.137).
Check the setting with [8C.Fn IV -1: Custom Controls] (p.231).
If the card’s writing speed is slow, movie shooting may stop
automatically. Use a card with a read/write speed of at least 8 MB per
sec. To find out the card’s read/write speed, see the card
manufacturer’s Web site.
If the movie file size reaches 4 GB or if the movie recording time
reaches 29 min. 59 sec., movie shooting will stop automatically.
The external flash does not fire.
The camera makes a noise when it is shaken.
The shutter makes two shooting sounds during Live View shooting.
Live View shooting is not possible.
The camera button/dial’s function has changed.
The movie shooting terminates by itself.
