Just bought the amazing HDR-XR500E HDD camcorder, slightly used. I already have a great external stereo microphone, with fluffy dog, but Sony has fitted a non-standard hotshoe. They call it the Active Interface Shoe 'to mount Intelligent Accessories - lights and microphones'. There is little in the manual on the subject.

Great if I finally buy the £170 bluetooth radio mic, but meanwhile I just want a mechanical mounting. I am searching the world for a suitable fitting as I cannot see a Sony designed adaptor. Anyone found or made one??
