[5] Manual or Stroboscopic Flash With a Siave Unit

Manual flash or stroboscopic flash can be set manually with a slave unit. The

setting is independent from the master unit. The master unit just triggers the
slave unit which fires according to its own independent (manual or

stroboscopic flash) setting. This feature can be used in the following

situations:

(1) As with studio flash, you can set the slave unit’s flash output yourself for

wireless manual flash photography.

(2) For wireless manual flash photography with Wireless Transmitter ST-E.
