I have a Canon 7D Mark ii, Pocket wizard plus iv's and several Canon 550 EX speedlites. I want high speed sync entirely off camera on multiple speedlites. High speed sync is only working when the speedlite is on the cameras hot shoe. I was informed by a Canon representative to use a ST-E2 transmitter. The problem is that it is not a radio. I prefer to use the pocket wizards. I read on Canons website that the 550 EX is not compatible.
"External Flash Settings - The camera can set the following with Speedlite 600EX-RT, 600EX, 430EX II, 320EX, 270EX II, 90EX, ST-E3-RT, or MR-14EX:External flash control".
The Canon representative did not tell me this. I do not want to waste money purchasing equipment that is not compatible so my question is, Should I upgrade all of my speedlites or should I purchase the ST-E2 transmitter? According to the website the 550 EX would not be compatibloe with any transmitter from my understanding of them.
