v4.300 addresses 5D Mark II performance issues and other performance improvements

July 10, 2009 - South Burlington, VT - PocketWizard has released the latest ControlTL firmware update; version 4.300. This update addresses several performance issues, especially with the Canon 5D Mark II camera and is recommended for all MiniTT1™ and FlexTT5™ owners. To install this update, simply connect your product to the PocketWizard Utility and click “check for updates” under the “maintenance” tab. If you do not have the Utility installed on your computer, it can be downloaded for free at www.PocketWizard.com/support/downloads.

The Canon 5D Mark II camera was introduced just before the introduction of the new MiniTT1 and FlexTT5 and the firmware running the new camera was significantly different then what was found in the other Canon cameras. It has taken some time to rework our firmware to work more consistently with the 5D Mark II while maintaining performance with all other compatible cameras. Version 4.300 is a major step forward for the overall system performance with any camera, including the 5D Mark II.

Key improvements in firmware version 4.300:

• ControlTL system will “auto-detect” the 5D Mark II camera. Photographers that previously had to craft C.1 or C.2 settings precisely for the 5D Mark II now have more flexibility. This also allows the system to use the optimized HSS settings without manually selecting the camera model in the PocketWizard Utility.

• “Forced TTL Master Mode” is now the default setting. This is the required setting for any flash on top of the camera mounted MiniTT1 or FlexTT5.

• Calibration shot does not trigger flashes. Triggering the flash during the first calibration shot is not needed so it has been turned off to save a little battery life.

• Several overall system performance improvements for the Canon 5D Mark II and other compatible cameras.
