With multiple Canon Speedlites having the wireless flash feature, you
can create various lighting effects with the same ease as using normal
E-TTL
II
autoflash.
The settings you input with the 580EX
II
(master unit) attached to the
camera are also automatically transmitted to the slave units which are
controlled by the master unit via wireless. Therefore, you need not
operate the slave unit(s) at all during the shoot.
The basic wireless set-up is illustrated below. All you need to do is set
the master unit to
<ETTL> enable wireless E-TTL
II
autoflash (p.37).
Note that with Type-A cameras prior to the EOS-1 0 Mark
II
and EOS
ELAN 7NE/ELAN 7N/30V/33V, E-TTL autoflash will be used instead.
Positioning and Operation Range
8m (26.2ft.) 12m (39.4ft.)

• Any flash exposure compensation, high-speed sync (FP flash),
FE
lock,
FEB, manual flash, and stroboscopic flash settings set with the master
unit will all be automatically transmitted to the slave units.
• Even with multiple slave units, all
of
them will be controlled
in
the same
way via wireless.
• A 580EX
II
set as a slave unit can also be controlled by wireless by
Speedlite Transmitter ST-E2 (optional).
• Hereinafter, the "master unit" will refer to a 580EX
1\
attached to the
camera, and a "slave unit" will be a wireless 580EX
II.
