On 2012-08-31, PocketWizard made firmware version 6.153 beta available for their MiniTT1 and FlexTT5 transceivers (for Canon). From the 6.153 release notes:
The following new Canon gear is supported in this beta firmware release:
- Canon EOS 5D Mark III
This equipment will work in the ControlTL® system similarly to previous Canon equipment.
So far I have tested the MiniTT1+AC3 to control the Einstein+PowerMC2 and 580 EX II + FlexTT5 and remote power control works correctly. The 6.153 beta firmware still requires you to half-press the shutter button after adjusting the power dial on the AC3 to ‘push’ and commit the power adjustment setting to the Einstein+PowerMC2.
HyperSync/HSS with the 580 EX II + FlexTT5 also works correctly.
So all my fellow PocketWizard TT1/TT5/AC3/etc owners that upgraded to the 5D Mark III can finally breathe a sigh of relief with the PocketWizard 6.153 beta firmware for the MiniTT1 and FlexTT5.
Upgrade advice for all PocketWizard TT1/TT5 users:
- Remember / record custom settings.
- Factory reset each unit.
- Update to the respective firmware.
- Factory reset each unit, again.
- Manually set all custom settings.
- Test PocketWizards to ensure everything is triggering.
Factory resets help to make sure the triggers are ‘clean’ after updating and ensures the best possible starting point when updating to a newer firmware. I always do the above steps and it mitigates any possible issues.
