When you add the PocketWizard AC3 ZoneController for Nikon to your on-camera MiniTT1 Transmitter or FlexTT5 Transceiver, you instantly have three zones of flash control. Whether in CLS/i-TTL or Manual mode, you have control over all your flashes from your camera position. Put your flashes wherever you want, without worrying about having to access them during a shoot.
Three clearly labeled dials let you increase or decrease power to three zones of flash in 1/3-stop increments with a range of up to six stops. Three switches allow you to change zones between Manual, Auto (PowerTracking / CLS/i-TTL) or OFF. Best of all, with its intuitive interface, the design is simple to use. When matched with the PowerST4 or AC9 AlienBees Adapter, you can now control Elinchrom RX, White Lightning and AlienBees flashes right from the camera's position.
All the PocketWizard radios in your system should be using the same firmware version for proper functionality. The AC3 for Nikon is compatible with any firmware version used on the MiniTT1 and FlexTT5 for Nikon.
