Troubleshooting Guide
Use a fully-charged battery pack (p.30).
The battery performance may have degraded. See [53: Battery info.]
to check the battery’s recharge performance level (p.364). If the
battery performance is poor, replace the battery pack with a new one.
The number of possible shots will decrease with any of the following
operations:
• Pressing the shutter button halfway for a prolonged period.
• Often activating only the AF without taking a picture.
• Using the lens’ Image Stabilizer.
• Using the LCD monitor often.
• Continuing Live View shooting or movie shooting for a prolonged
period.
Auto power off is in effect. If you do not want auto power off to take
effect, set [52: Auto power off] to [Disable] (p.57).
Even if [52: Auto power off] is set to [Disable], the LCD monitor will
still turn off after the camera is left idle for 30 min. (The camera’s
power does not turn off.)
The camera cannot be used with EF-S lenses (p.43).
Install a recharged battery pack in the camera (p.34).
The battery becomes exhausted quickly.
The camera turns off by itself.
