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.
With PocketWizard HyperSync™ Technology, the FlexTT5 can precisely advance the timing of your flash trigger so that increased flash sync speeds, up to 1/500th of a second is achievable with many strobes.
Need more speed? Push your ControlTL system beyond 1/500th and go into FP/High-Speed sync mode automatically. Simply change your shutter speed to get flash sync all the way to 1/8000th. No buttons to press or settings to change!
* ControlTL™: PocketWizard’s newest firmware platform taps into the camera’s digital communications to enable an entirely new level of remote flash capability through our proven radio system. ControlTL allows remote TTL for Canon E-TTL II systems as well as Manual Power Control. ControlTL firmware is configurable and upgradeable for “future-proof” continuous improvement. Find more details on ControlTL here.
* Dedicated E-TTL II Triggering: Locking your MiniTTI Transmitter into the hot shoe of a Canon DSLR camera and mounting E-TTL II flashes onto FlexTT5 Transceivers gives you full autoflash exposure control with the freedom and reliability of a PocketWizard radio. There are no special settings to make or modes to call up. Use the camera, on-camera flash or flash commander controls for flash compensation, zone and ratio control.
* Manual Power Control: Adjust the manual power settings of your remote Canon Speedlites directly from a 580EX II flash mounted on your on-camera MiniTT1 or FlexTT5. Working with a Canon 580EX II in the shoe of the MiniTT1 or FlexTT5, you can independently control the power output of up to three groups of lights (you can have as many lights in each group as you want) from full power down to the lowest setting simply through the user interface on the back of the 580EX II. Now you can work with total control with your remote lights, without leaving your shooting position.
* Zone Select: The FlexTT5 Transceiver has an A-B-C zone select switch to allow use with the remote groups/zones found on on the PocketWizard AC3 ZoneController or Canon flashes. Zones allow you to control single or groups of lights independently from other lights in different zones. These zones can also be used with a MuiltiMAX thus allowing you to pair a single MultiMAX radio on camera with FlexTT5's Transceivers on your remote flashes and utilize many of the MultiMAX's advance trigger functions.
* HyperSync™: HyperSync allows photographers to achieve faster X-sync speeds with full power flash. Now you can cut the ambient light and use wide-open apertures, outdoors in bright sunlight. That extra speed can also freeze action, whether shooting models or athletes in motion.
HyperSync works with both TTL speedlites and full size studio flash. All you need is a MiniTT1 or FlexTT5 on camera that has been tuned to your specific camera via the PocketWizard Utility. While performance varies by the camera and flash equipment being used, HyperSync will get the maximum possible out of any set-up.
* Optimized High SpeedSync (HSS): When HyperSync can’t keep up, High Speed Sync takes over for Speedlite flash photography all the way to 1/8000. ControlTL optimizes this amazing feature and provides more light (which equals greater working distance), faster recycling times and more flashes per battery set when shooting in Canon's HSS/FP Flash mode. Use this feature to shoot wide open in bright sun for amazing results.
