I'm surprised that there was enough current to blow up a dynamic mic.
You just have just been unlucky. But given that the camera input is
single-ended (not balanced), the powering voltage is applied directly
across the microphone output rather than it being cancelled out by the
standard phantom powering scheme.

Pretty sure that there is a menu somewhere to do this on the 800E. They
don't force you to use an electret.

I'll check mine.
