Hi, I've a Nissin 466 for Olympus/Panasonic which is working perfectly if directly attached to my Lumix G3. If I try to use it with a TTL flash cord (~ 2 meters, Meike China brand for Canon) the flash is not working. The camera recognizes the attached flash (setting the synchro time), but automatic zoom reflector is not working anymore. And the flash will not lit. I tested the cable, all contacts are ok (measured with multimeter). The cable is already modificated so the middle contact is not blocked by the internal diode. Any ideas? Anybody out there with a working combination of Nissin 466 and a TTL cable?
