PocketWizard AC3 Zone Controller for Canon

Control your flash

The AC3 ZoneController for Canon is the gem of the ControlTL product line and allows you to be in total control of your flash. 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 or Manual mode, you now have control over all your flashes directly from the camera’s position. With three simple dials, you can quickly adjust the power settings for three independent zones in 1/3rd stop increments with a six stop range.

Put your flashes wherever you want, without worrying about having to access them during a shoot. PocketWizard’s new firmware platform taps into the full potential of your camera and flash system enabling an entirely new level of remote flash capability through our proven radio communications. ControlTL firmware is configurable and upgradeable for “future-proof” continuous improvement. SpeedCycler, previously only seen with PocketWizard’s MultiMAX radios, this new mode is designed to rapidly cycle through multiple flash units fired individually in sequence. This allows photographers to fire a camera in sync with flashes faster than a single flash unit can recycle.It can also be used for triggering remote cameras sequentially. SpeedCycler is engaged on a transmitting MiniTT1 or FlexTT5 via the PocketWizard Utility.

SpeedCycler mode requires an AC3 ZoneController in the top hot-shoe of the on-camera PocketWizard radio.Zones A, B, and C will be triggered sequentially and individual zones can be disabled by setting the AC3’s Zone Switch to the off position. Both TTL and manual flash controls are supported. Photographers can now take their AC3 and transmitting radio off-camera and use it to set power levels for any flash with a ControlTL receiver, making it more convenient to use an optically triggered light meter, or control the power levels with just a MiniTT1/FlexTT5 and AC3 in their hand while another photographer takes the pictures. Previously, an AC3 ZoneController on a MiniTT1 or FlexTT5 needed to be on camera to send manual power levels to remote flashes. Now, when connected to a MiniTT1 or FlexTT5, manual power levels are transmitted to remote flashes when the TEST button is pressed even when the transmitter is off the camera. This affects both speedlights connected to receiving FlexTT5s and larger flashes like AlienBees and Elinchrom RX units with ControlTL receivers.
