Hi,
I had the same problem with my fx1 and the 2100e uwhen seinhisser 300d mounted it picks up motor noide and any knocks your tripod gets are amplified I made up a bracket to mount the mic off camera suspended in elastic bands, Problem solved. Steer clear of AC units in hotels or other recording locations as mic will pick up motor and air hum.
I also have the Z7 And there are no such problems as the supplied mike is mounted in a foam rubber slieve.
Hope this helps
