I posted this a few minutes ago on a topic that was similar regrading pocket wizard beta update 6.153. Hope this helps because I know it's been driving me crazy since up got my 5d3.
First time poster long time lurker. Want to say thank you for this post Justsomedude. I've been waiting for this firmware update for months as I have missed some of the functions that pocket wizard offers. Manly the AC3 zone adaptor. I would also like to say thanks to a few posters that I have learned so much from in the past. Namely Bosman, Mt. Spokane Photography, Neuroanatomist, and V8Beast to name a few. I can confirm that the Flex TT5 and Mini TTI along with the AC3 zone adaptor seem to work with the 5D3 and 600EX-RT's. You can use the AC3 to fire the flash in different groups and also adjust the power setting for both manual and ETTL. I've only ran a few tests. One of the things that I did notice is that while the flash seems to fire on the power setting you set from the AC3 the back screen on the 600 doesn't change. It says it's in ETTL at no compensation. Even when you are in Manuel and power the flash all the way down on the AC3. I also noticed that the IR beam doesn't work to help focus on the flashes. You might be wondering why I would need the pocket wizards if I paid the money to get the radio function in the 600. It basically comes down to the fact that I have ST-E3-RT and while it's great it is not as simple to change power settings, zones, manuel to ETTL in different zones as the AC3. Second reason is that I also have a couple Einsteins that I love to use with the Canon flashes and again the AC3 has no equal that I've seen. I will be doing a larger test tomorrow at the beach with my kids to see if some of the old problems pop up that I use to have with the 580's. I'll post the results. Thanks again....
