NB at the Canon EOS 600D, the Rode sounds alone miserable. This is, however, less than the microphone itself at the
internal AGC of camera. Through this "Automatic Gain Control" the noise is enormous. Unfortunately, you can not AGC of 600d
manually deactivate - also a known software (ML) provides currently no workaround to this problem (though works
at 550, or 7d).
What surprised me a little: The packaging of the microphone was not sealed and I had somehow the impression that I
not the first consumer was that it unpacked (the factory tests disregarded). Hm. Who knows.
