PocketWizard AC3 ZoneController Fingertip Power Control for Nikon i-TTL

Key Features

• ControlTL: 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 the proven radio communications. ControlTL firmware is configurable and upgradeable for future-proof continuous improvement
• i-TTL Compatibility: Designed to work seamlessly with Nikon's i-TTL system, the AC3 ZoneController removes operating complexity with its easy-to-use design
• Manual Power Control: 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
• ZoneControl: Control up to three zones of light, each with one or more flashes, right from the camera's position. Set them all on manual, auto, or mix the settings between zones. Need to turn a zone off? Just slide a switch and it's off
• PowerTracking: In Auto Mode, change ISO, aperture, or FEC and the lights automatically adjust their compensating power setting with PocketWizard PowerTracking
• Studio Flash Compatibility: When used in conjunction with a PowerST4 Receiver for Elinchrom RX, or a FlexTT5 paired with an AC9 AlienBees Adapter, you have remote power control over Elinchrom RX, AlienBees and White Lightning studio flash
• Simple Design: The AC3 weighs almost nothing and slips into the top-shoe of your on-camera MiniTT1 or FlexTT5. There are three dials and three switches, one for each zone
• Auto-Manual Switch: This switch allows you to set each zone to either Manual Power Control, Auto or Off. Set it to off and that zone will not fire
• Easy to read dials: Clearly labeled from +3 to -3 in 1/3rd stop increments. In Auto mode, the dials act as flash exposure compensation. In manual mode, +3 on the dial is your flashes maximum power level
