Severe noise!

I bought the microphone to improve the quality of the sound on my Nikon D800. Unfortunately I have to say this is the sound with this microphone even slightly worse. The level is so low, that needs to be massively reinforced in the camera. The noise is thus also with reinforced and is extremely disturbing. With automatic level adjustment is most unsatisfactory. The cushioning on the holder is also insufficient. Operations at the camera while shooting will greatly received. At the Zoom H1 Handy Recorder is slightly better. However, still too bad for seriously-increasing video recordings. If you want better quality here has to reach a little deeper into their pockets. For me, it boils down to a Sennheiser MKE 600 also.
