Set [A3: Auto Lighting Optimizer] to [Disable]. When [Standard/
Low/High
] is set, even if you set a decreased exposure compensation
or flash exposure compensation, the image may come out bright (p.159).
If you shoot at night when the background is dark, the shutter speed
becomes slow automatically (slow-sync shooting) so that both the
subject and background are properly exposed. To prevent a slow
shutter speed, under [A1: External Speedlite control], set [Flash
sync. speed in Av mode] to [1/200-1/60 sec. auto] or [1/200 sec.
(fixed)] (p.221).
If you use a flash unit other than an EX-series Speedlite, the flash will
always be fired at full output (p.293).
Under [A1: External Speedlite control], if [Flash metering mode]
under [Flash C.Fn settings] is set to [TTL], the flash will always fire at
full output (p.224).
If flash exposure compensation has been set on an external Speedlite,
[Flash exposure compensation] (p.223) cannot be set in the [Flash
function settings] screen. Also, if you set flash exposure
compensation with the camera and then set flash exposure
compensation with the external Speedlite, the Speedlite’s flash
exposure compensation setting will be given priority. When the
Speedlite’s flash exposure compensation is canceled (set to 0), [Flash
exposure compensation] can be set with the camera.
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 flash always fires at full output.
I cannot set flash exposure compensation with
[Flash function settings].
