#1. "RE: Commlite TTL flash trigger" In response to Reply # 0
First, I have never used or even seen anything other than a photo of the Commlite triggers. After searching the web, it appears that the T320, G430, and H550 are Manual flash triggers. They list "TTL Pass-Thru" which means that if you mount the Trigger in your cameras hotshoe and place an i-TTL compatible Speedlight in the hotshoe of the On Camera trigger, the TTL signals from the camera will pass thru the Trigger to the attached Speedlight.
The TL680 appears to have wireless TTL capability though how well it actually works; I have no idea.
I have Pocket Wizards and they work very well and I have been very happy with them and recommend them.

Thank you for your information.
I haven't had the need for high-speed sync. $400 for a pair of RF trigger-receiver set is kind of non-sense to me. Therefore I was just wondering if anyone has ever tried alternatives (and I very much believe someone must have).
I am trying Yongnuo's trigger and flashes with built-in receiver. Its trigger with 16 channels only costs like $20. So far I like them. The only complaint I have on its trigger is that it does not allow TTL pass-through. I expect Commlite's trigger and receiver sets should work to the same degree.
Question: How reproducible is the high-speed sync by Pocket Wizard?
