Pocket Wizard has updated the firmware for the FlexTT5 and MiniTT1 flash triggers for Canon DSLRs. Firmware v4.250 adds a number of enhancements:
â€¢ Boosts the High Speed Sync feature of Canon Speedlights
â€¢ Provides energy savings for faster recycling, more shots per battery while enabling greater working distances.
â€¢ 5D Mark II now compatible with on-camera flash with ControlTL system.
The new firmware also allows photographers to disable HyperSync mode in the MiniTT1 and FlexTT5, allowing use of HSS for shutter speeds down to 1/320 second. This is especially useful for the Canon 5D and 5D MK II whose shutter mechanisms canâ€™t take full advantage of the HyperSync mode.
