The AC3 ZoneController for Nikon (and Canon) is the gem of the ControlTL® product line. Add it to your on-camera MiniTT1® Transmitter or FlexTT5® Transceiver and you instantly have three zones of flash control. Whether working in E-TTL II, CLS/i-TTL or Manual mode, you now have control over all your flashes directly from the camera’s position. Put your flashes wherever you want, without worrying about having to access them during a shoot. With the AC3 ZoneController, you are in total control of your flash.
Three clearly labeled dials allow you to 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, E-TTL II, CLS/i-TTL) or OFF. Best of all, the design is simple with an intuitive interface. When matched with the PowerST4 or AC9 AlienBees Adapter, you can now control ElinchromRX1, White Lightning2 and AlienBees2 flashes right from the camera’s position.
• Three independent zones of flash control
