Contents Foreword
Thanks for your purchase of this ST-III S TTL wireless flash trigger.
This TTL wireless flash trigger only applies to SONY cameras. It can also directly control
flashes which have built-in Pixapro wireless ONE system (e.g. Li-ion580II S, HyBRID360
TTL , CITI600 TTL, CITI600 Manual, STORM II, etc.). As to the flashes which do not
have Pixapro (e.g. Li-ion580, HyBRID360, etc.), a PRO AC 2.4GHz or ST-I 2.4GHz
receiver can be used in combination to achieve manual flash control. Featuring multi-
channel triggering, stable signal transmission, and sensitive reaction, it gives
photographers unparalleled flexibility and control over their strobist setups. ST-III T-S
can also connect to the cameras which have PC sync sockets. It supports high-speed
sync function and the max flash synchronization speed is up to 1/8000s *.
*: 1/8000s is achievable when the camera has a max camera shutter speed of 1/8000s.
