PocketWizard has released their latest Canon firmware update 6.200 for their ControlTL radios which include the MiniTT1 and FlexTT5. This is the long awaited update that the company has quite literally put a ton of resources into. By updating, users will finally be able to set up their Canon 5D Mk III with the two radios. Head on over to their download page for the update. (PocketWizard Utility 1.54 or later is required to install through USB).
For Canon EOS-1D X and T4i users, a separate update should be coming soon.
