Wireless Multiple Flash
This chapter describes how to perform wireless multiple
flash shooting with optical transmission, using an EX-
series Speedlite (sold separately) equipped with
wireless receiver function.
For the accessories required for wireless multiple flash
shooting, see the system map on page 68.
When the camera's shooting mode is set to a fully automatic
mode or an Image Zone mode, the operations in this chapter are
not available. Set the camera's shooting mode to d/s/f/a/
F (Creative Zone mode).
The MR-14EX II attached to the camera is called "sender", and
the Speedlite (external flash unit) controlled wirelessly is called
"receiver".
