PocketWizard’s AC9 AlienBees Adapters are the latest accessory for the PocketWizard MiniTT1 and FlexTT5 ControlTL radio system. The AC9 slides into the shoe of a PocketWizard FlexTT5 and enables remote power control of AlienBees or White Lightning flashes with a camera-mounted PocketWizard MiniTT1 Transmitter or FlexTT5 Transceiver. Utilizing PocketWizard’s ControlTL technology, you can control the flash power level using the camera’s Flash Exposure Control (FEC). The AC9’s PowerTracking feature automatically adjusts flash power to maintain the established level to maintain proper exposure whenever the aperture and/or ISO is changed. Sliding the PocketWizard AC3 ZoneController into the shoe of the camera mounted MiniTT1 or FlexTT5 enables controlling AlienBees or White Lightening flash units in three zones, A B C, in 1/3-stop increments over a six-stop range. The AC9 draws its power directly from the FlexTT5 so there’s no need to install or replace batteries. The PocketWizard AC9 is a must-have for Canon and Nikon photographers using PocketWizard with AlienBees units.
