I purchased this microphone to use with my Sony HDR-HC7. My main reason for buying this mic was for improved off-axis sound rejection when recording speech in noisy environments. The shotgun design of this microphone, and it's corresponding directional polar response naturally means that it's considerably better than the camcorders built in omni mic at rejecting sounds which aren't coming from directly in front of the camera. The main disappointment however, is that the ECM HGZ1 has a very poor low frequency response, to the point of sounding quite tinny. I'd say that this mic does have it's uses, but unless you're regularly recording sound in very noisy locations, or perhaps where wind noise might be causing problems, then you may well get better results with the mic in your camcorder.
