The AC3 ZoneController for Canon and Nikon 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 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.
| Nikon | Canon |
Features:
- Three independent zones of flash control
- 6 stops of flash control in 1/3rd stop increments
- Works in PowerTracking, E-TTL II, CLS/i-TTL or Manual mode
- Turn zones on and off remotely
- Works with Canon or Nikon Speedlights, AlienBees, White Lightning,Elinchrom RX flash and Einstein™ E640 flashes.
- Put your flashes where you want, without worrying about accessing them during a shoot.
Operation:
Make sure the camera is awake (half-press the shutter button) when changing settings to assure AC3 settings are transmitted to remote ControlTL radios.
Mode Switches
- 0 = OFF - Flashes will not trigger. Set unused zones to 0/.
- M = Manual Mode - ControlTL compatible flashes will use the manual power output value set on the AC3 Power Dial. See the power dial chart below for more info.
- A = Auto Mode - ControlTL compatible flashes will use the Flash Exposure Compensation (FEC) as set on the AC3 Power Dial. Nikon Speedlights will perform i-TTL exposures. When compatible studio flashes are used, PowerTracking will engage (see PowerTracking section in AC9 AlienBees Adapter, PowerST4 or PowerMC2 Quick Guides for more information).
Manual and Auto modes can be used at same time. Manual zones will not be calculated as part of the E-TTL exposure. Zones set to 0/ (OFF) will not trigger.
FEC NOTE: In Auto Mode, Flash Exposure Compensation (FEC) can be set in more than one place and the values are used together - all positive and negative FEC values will be combined.
- FEC can be set:
- On each zone independently using the AC3 Power Dial when the zone is set to A (Auto)
- On each remote Speedlite using the camera’s FEC control. All AC3 zones set to A (Auto) will be affected equally.
If the combined FEC adjustments are more or less than your flash’s capabilities, then the flash will operate at maximum or minimum output accordingly
