The dedicated FlexTT5™ Transceiver, with its built in hot-shoe and ControlTL™ firmware, is the perfect addition to Canon E-TTL II flash systems. The FlexTT5 takes the existing benefits of Canon wireless systems beyond the boundaries of infrared technology. When paired with the Mini TT1™Transmitter or another FlexTT5 Transceiver, a whole new world of wireless flash freedom opens up. The FlexTT5 is also the perfect Transceiver for your manual triggering needs and works with all MultiMAX channels and many of the MultiMAX advanced functions.

The FlexTT5’s simple design comes to life through its hot-shoe connection with a camera or flash. Mount a flash or command unit on the FlexTT5 to use the same zone controls and ratio commands as you would normally. The system tracks your changes in ISO, shutter speed and aperture and reacts accordingly to make sure exposures stay right on target. Use the flash compensation dial on your camera or flash just as you would normally and the changes pass seamlessly through the system.

The FlexTT5 has two channel configuration settings; C1 and C2. Each can be programmed as needed with up to 20 ControlTL channels* for TTL photography, or 32 standard channels** for manual flash photography. The FlexTT5 Transceiver also has a three-zone selector switch for ease of use with Canon zones and ratios.
* - 20 ControlTL channels for FCC/IC 344 MHz radios and three ControlTL channels for CE 433 MHz radios.
** - 32 Standard channels for FCC/IC 344 MHz radios and 35 Standard channels for CE 433 MHz radios.
With PocketWizard's patent pending HyperSync™ Technology, the FlexTT5 allows you to use sync speeds beyond your camera's x-sync, up to 1/8000th of a second with some camera/strobe combinations, giving you the control you've always been looking for. With ControlTL Firmware Upgrade 6.0, HyperSync is automated and HyperSync timing is now adjusted in two seperate places - on the transmitter and on the receiving ControlTL radio. The transmitting or on-camera MiniTT1 or FlexTT5 automatically adjusts HyperSync to compensate for changes made to shutter speed. Photographers can further refine HyperSync via the PocketWizard Utility. Learn more HyperSync Automation at wiki.pocketwizard.com/hypersync.
You can also use your camera's FP/High-Speed sync mode with Canon Speedlites with the convenience and freedom of radio reliability. Now you can use any shutter speed or f-stop you want no matter where you place your flash.

The FlexTT5 also has our Auto-Sensing Transceiver Technology that enables it to switch back and forth between Transmitter and Receiver modes as needed for greater flexibility on the job. When a hot-shoe or other trigger is detected, it automatically switches to Transmitter mode. With Auto Relay Mode you can easily trigger a remote camera in sync with remote flash. Put a camera where you can’t be and use remote TTL or non-TTL lighting at the same time. Expand your coverage and increase your creativity.
