Using the VS-570 as a Wireless TTL Slave
The VS-570 can be used as an optical wireless TTL slave in Sony, Nikon, and Canon TTL systems. This enables
you to use a Sony, Nikon, or Canon wireless TTL master to control the VS-570 as a slave flash unit.
To set the wireless TTL slave mode, follow these steps:
1. Make sure the master flash or controller on your camera is turned on and set to automatic TTL mode.
2. Select the appropriate group and channel on the master unit. Consult the master’s user manual for more
information on this topic.
3. Press the VS-570’s Mode button repeatedly to cycle through the
flash modes until the Wireless TTL mode [ ] icon appears on the
LCD. Use the up or down navigation buttons to select Sony, Nikon, or
Canon TTL slave modes.
A. For Sony TTL slave mode, the S-TTL indicator will appear
onscreen. Press the Mode button to confirm, and the LCD will
display the Sony optical slave screen. To set the VS-570 as a Sony
TTL slave, continue with Sony TTL Slave Mode on page 37.
