About Wireless Flash

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 (master unit) attached to the camera are also transmitted to the slave units which are controlled by the master unit via wireless. Thus, you need not operate the slave units at all during the shoot. The basic wireless set-up is illustrated below. Then all you do is set the master unit to <ETTL> and wireless E-TTL II autoflash will be enabled (p.34). Note that with Type-A cameras prior to the EOS-1D Mark II and EOS ELAN 7NEI ELAN 7N/30V/33V, E-TTL autoflash will be used instead.
