To perform flash shooting, set to [Enable]. To use the flash’s AF-
assist beam only, set to [Disable].
E-TTL II flash metering
For normal exposures, set it to [Evaluative].
If [Average] is set, the flash exposure will be averaged for the entire

be necessary depending on the scene. This setting is for advanced
users.

AE (Av) mode with flash.

You can select the flash mode from [E-TTL II], [Manual flash],
[MULTI flash], [AutoExtFlash] and [Man.ExtFlash] to suit your
desired flash shooting.
When the flash’s Custom Function C.Fn-05 is set to [1:TTL] (p.96),
[TTL] can be selected. When performing autoflash shooting with an
EOS digital camera, set to [0:E-TTL II/E-TTL].

curtain] and [High-speed synchronization]. To perform normal
