[ccting]

Please help me to choose. Thanks very much. Planning to buy very very soon.



Making a classic trigger better! The Phottix Strato II Multi 5-in-1 Wireless Trigger System gives
photographers incredible control over their flashes and studio lights. Four channels and four groups
provide unparalleled control in the studio or on location. The Strato II Multi can be used as a wired or
wireless shutter release. The 2.4 GHz. transmitter and receivers offer ranges of more than 150 meters
and sync at speeds of 1/250 second .*

Transmitters feature an innovative TTL pass-through hot shoe - allowing full TTL mode to be used with a
camera mounted flash. Receivers offer flash wake-up functions.*

That means wireless TTL enabled? So i need multiple TTL speedlights and use them as off-camera TTL flash? I don't quite understand this...what is the difference between the rest (see title). Ty.
