HVL-F28RM
Multiple wireless flash photography (group flash photography)
You can perform wireless flash photography among a maximum of 5 wireless groups of flash units including the commander unit.
Before you perform multiple wireless flash photography, be sure to configure each of the flash units as the commander unit or the
receiver unit.
Commander unit: this flash unit (HVL-F28RM) or a radio wireless commander
Receiver unit (off-camera flash unit): this flash unit (HVL-F28RM) or a radio wireless receiver
Hint
You can specify [TTL Flash Firing], [Manual Flash Firing], or [Flash Off] for the flash control mode of the wireless groups A, B, and C. For
the wireless groups D and E, on the other hand, you can specify either [Manual Flash Firing] or [Flash Off]. The flash units in the wireless
group with the flash mode specified as [Flash Off] do not fire flashes. This flash unit cannot be specified as a member of the wireless group
D or E.
When [On] is specified for the TTL level memory function ([TTL Level Memory]), the flash power level measured during TTL flash
photography is automatically applied to the flash power level for each of the wireless groups A, B, and C during manual flash photography.
The commander unit fires flashes as a member of the wireless group A. When you do not want the commander unit to fire flashes, select
[External Flash Set.] - [Ext. Flash Firing Set.] - [CMD Flash Firing] from the menu of the camera attached with the commander unit, and
then specify [Off].
You can compensate the flash power level collectively for all the wireless groups by specifying a collective flash compensation level.
