Ultimately, I then very reason chose five Pocket Wizards Plus III, in the knowledge that that no ADI / TTL is possible and I have set up my home studio flashes manually. However: As soon as you use more than one flash, one must, in my opinion his lightning anyway manually. In addition I have done me the Sekonic L-478DR compatible and am very satisfied - triggering the PocketWizard Plus III with the light meter works perfectly. All the way I want.
Yes, as long as one does not use Sony flashes, because they did not own PC / Sync sockets and unfortunately I have found to date no functioning Blitzadapter - see also my review of Kaiser 1303 (NOT work). I have now ordered a few Yongnuo flashes and will report of my experience.
In just a flash, I'm working with WL mode via infrared with SONY-flashes, it works well.
The PocketWizard Plus III itself - work extremely simple and reliable with 32 channels and 4 zones - more you do not need.
The new test button with the intermediate step for remote focusing during unleashed camera triggering works in the A77, only when pressed all the way in the A55.
Résumé: Unleashes flashes as SONY user a difficult undertaking, the PocketWizard Plus III has, however, something that works soothing harmless.
