We recently released the latest official ControlTL firmware, version 5.10. Based on continued internal testing and feedback from users, it appears a couple of the exposure and timing data tables became corrupted somewhere in the process. We’ve had reports of improper exposures with several camera models as well as shutter clipping with the Canon 1Ds Mark III and 1D Mark IV. We have corrected the tables and the revised firmware is available as version 5.15 and can be downloaded via the PocketWizard Utility now.
We recommend upgrading to 5.15 as soon as you can.
The manual addendum for v5.10 is still the same for v5.15.
