3 Setting the Flash
FEB
While the flash output is changed automatically, three flash shots are
taken. For details, see the instructions for FEB (Flash Exposure
Bracketing) in your Speedlite’s instruction manual.
Flash exposure compensation
The same setting as “Flash exposure compensation” on page 119
can be done.
E-TTL II
For normal flash exposures, set it to [Evaluative].
If [Average] is set, the flash exposure will be averaged for the entire
metered scene as with an external metering flash. Since flash
exposure compensation may be necessary depending on the scene,
this setting is for advanced users.
Zoom
You can adjust the Speedlite’s flash coverage. Normally, set this to
[Auto] so that the camera will automatically set the flash coverage to
match the lens focal length.
Wireless setting
Wireless flash (with multiple flash units) is possible. For details, see
your Speedlite’s instruction manual about wireless flash.
Flash firing
To enable flash photography, set [Enable]. To enable only the AF-
assist beam to be emitted, set [Disable].
When using 2nd-curtain sync, set the shutter speed to 1/50 sec. or slower. If
the shutter speed is 1/60 sec. or faster, 1st-curtain sync will be applied even
if [2nd curtain] is set.
If flash exposure compensation has already been set with the Speedlite,
you cannot use the camera’s button or Flash function settings
menu to set flash exposure compensation. If it is set with both the
camera and Speedlite, the Speedlite’s setting overrides the camera’s.
The flash function’s [E-TTL II] setting will work together with C.Fn II -5
(p.215). And [Flash firing] will work with C.Fn II -7 (p.216).
