I need help with something, I'm trying to use the ST-E2 as a wireless transmitter for my new to me Dynalite strobe system. The unit has an internal receiver that the instruction manual says is for a Pocketwizard transmitter. The problem is that the strobe is firing a nanosecond before my 5D shutter opens. It syncs fine with the sync chord. Any thoughts? I was hoping the canon transmitter I already have can be synched to the unit, but maybe I need another purhase.
