New firmware for the PocketWizard FlexTT5 transceiver and the MiniTT1 transmitter for Canon is available now. ControlTL Version 5.1 offers compatibility with the AC3 ZoneController. The AC3 ZoneController for Canon gives the photographer control over three independent zones of light, whether working in E-TTL or Manual mode, directly from the cameraâ€™s position.
The update also adds compatibility with the Canon EOS Rebel T2i, extends compatibility with the EOS 7D and EOS 1D Mark IV, and fixes bugs.
The company cautions the user to always perform a factory reset after updating the firmware. Also, to write down any custom settings for Configuration 1 or Configuration 2 before resetting the radios to re-apply them after the upgrade.
