Optical Transmission Wireless Flash Photography - Canon Speedlite 470EX-AI Instruction Manual

: Optical Transmission
Wireless Flash Photography
Using a Canon device equipped with an optical transmission wireless
sender function and 470EX-AI set as a receiver unit, you can easily
take pictures with wireless multiple flash lighting in the same way as
normal E-TTL II/E-TTL autoflash photography.
The system is designed so that the settings of the sender unit are
automatically applied to the wirelessly controlled 470EX-AI (receiver).
Therefore, you do not need to operate the receiver unit during shooting
(except when set as the individual receiver, p.79).
For details on how to perform optical transmission wireless flash
photography, refer to the Instruction Manual of the device equipped with
the sender function.
