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.
