Warning for Canon 400D (Digital Rebel Xti) with Heinrichs eTTL-Converter
Underwater photographers, who work with a Canon EOS 400D and eTTL-Converter developed by Heinrichs-Weikamp, are asked to kindly not update the firmware of their camera for the time being. With the recent firmware-update offered by Canon the camera will become incompatible with the eTTL-Converter. This situation also affects recent amphibic eTTL flash guns offered by Subtronic, a manufacturer who installs the converter as an OEM-version in their strobes. The problem currently only occurs with a Canon EOS 400D (Digital Rebel Xti). Other camera models are not affected by this. Heinrichs-Weikamp labs are currently working on a solution. However it might be necessary to mail-in housings or strobes for an upgrade to solve the issue.
