Troubleshooting Guide

The built-in flash is raised by itself.

In shooting modes (<A> <C> <2> <4> <6>) whose default settings are <a> (Auto flash), the built-in flash will rise automatically when necessary.

The built-in flash does not fire.

If you shoot continuously with the built-in flash at short intervals, the flash may stop firing to protect the flash unit.

The flash always fires at full output.

If you use a flash unit other than an EX-series Speedlite, the flash will always be fired at full output (p.271).

Under [z1: Flash control], if [Flash metering mode] for [External flash C.Fn setting] is set to [TTL], the flash will always fire at full output (p.197).

I cannot set flash exposure compensation when using an external Speedlite.

If flash exposure compensation has already been set with the external Speedlite, flash exposure compensation cannot be set with the camera. When the external Speedlite’s flash exposure compensation is canceled (set to 0), flash exposure compensation can be set with the camera.

High-speed sync cannot be set in the <f> mode.

Under [53: Custom Functions (C.Fn)], set [3: Flash sync. speed in

Av mode] to [0: Auto] (p.259).
