Wireless Flash: Optic Transmission
This product is compatible with Nikon Creative Lighting System (CLS). It can function as either an optic
wireless master or slave flash. As a master unit, it can control Nikon speedlights e.g. SB-900 and SB-910
via wireless. As a slave unit, it can be controlled by wireless signals of Nikon speedlights e.g. SB-900 and
pop-up flash commanders of Nikon cameras e.g. D7100/D7000/D800.
●
You can set up three slave groups for i-TTL autoflash shooting. With i-TTL autoflash, you can easily create
various lighting effects.
●
Any flash settings for the slave units on the master flash in i-TTL/Manual/RPT mode will be automatically sent to
the slave units. So the only thing you need to do is to set the master unit for each slave group without any
operation for the slave units at all during the shooting.
●
This flash can work in i-TTL/M/RPT/OFF flash modes when set as a master unit.
