Wireless multiple flash can be operated in two ways: (1) In the A (auto) mode, in
which the wireless slave flash units start and stop firing in sync with the master
Speedlight, and (2) in the M (manual) mode, in which the wireless slave flash
units only fire in sync with the master Speedlight.
nIn wireless multiple flash, the master flash unit triggers and controls the flash duration of
the slave flash unit(s).
nThe camera’s built-in Speedlight can also be used as a master flash unit.
nSpeedlights compatible with TTL auto flash, but having no wireless multiple flash function,
can be used as the master flash unit. The optional Wireless Slave Flash Controller SU-4
allows you to use any Speedlight as a slave flash unit.
