Troubleshooting Guide
Set [z2: Auto Lighting Optimizer] to [Disable]. When [Low],
[Standard], or [High] is set, even if you set a decreased exposure
compensation or flash exposure compensation, the image may come
out bright (p.146).
If you shoot at night when the background is dark, the shutter speed
automatically becomes slow (slow-sync shooting) so that both the
subject and background are properly exposed. To prevent a slow
shutter speed, under [z1: Flash control], set [Flash sync. speed in
Av mode] to [1/200-1/60sec. auto] or [1/200 sec. (fixed)] (p.184).
In shooting modes (<A> <C> <2> <4> <C> <6>) whose
default setting is <a> (Auto flash), the built-in flash will be raised
automatically when necessary.
In the <x> and <G> modes, when you press the shutter button
halfway under low-light conditions, the built-in flash may be raised
automatically and emit the AF-assist beam.
If you use the built-in flash too often in too short a period of time, the
flash may stop firing for a while to protect the light-emitting unit.
If you use a flash unit other than an EX-series Speedlite, the flash will
always be fired at full output (p.182).
Under [z1: Flash control], if [Flash metering mode] in [External
flash C.Fn setting] is set to [TTL flash metering] (autoflash), the
flash will always fire at full output (p.188).
Even though I set a decreased exposure compensation,
the image comes out bright.
When I use the <f> mode with flash, the shutter speed
becomes slow.
The built-in flash rises by itself.
The built-in flash does not fire.
The external flash always fires at full output.
