Troubleshooting Guide
Even after I change the card, the maximum burst displayed for
continuous shooting does not change.

The maximum burst displayed does not change when you switch cards,
even if you switch to a high-speed card. The maximum burst shown in
the table on
=
615 is based on Canon’s testing card. (The faster the
card’s writing speed, the higher the actual maximum burst will be.) For
this reason, the maximum burst displayed may diff er from the actual
maximum burst.
Even if I set a decreased exposure compensation, the image
comes out bright.

Set

compensation or fl ash exposure compensation, the image may come out
bright.
I cannot set the exposure compensation when both manual
exposure and ISO Auto are set.

Shooting with the fl ash may be temporarily disabled to protect the fl ash
head if the built-in fl ash is used repeatedly over a short period.
