The PocketWizard Plus II units will only trigger your flashes, and will do nothing for remote power control, nor for ETTL exposure metering and the remote power control then required to get the exposure to happen. From Pocket Wizard you need the more expensive Flex TT5 for the remote flashes, and either the Flex or a Mini TT1 unit for the camera. With those units you get remote manual power control, and full ETTL flash photography. And the AC3 accessory only works with the Flex units. All of that is expensive compared to the Plus II triggers.
