Rainer Hönle, who runs gletscherbruch.de and goes by the name nightshot in forums, is certainly the one to contact with such an issue. He's well known and highly regarded as someone who is able to fix even the weirdest problems with canon gear. Especially those issues that Canon itself seems unable or unwilling to fix.
