There are situations when the in-camera microphone is not directed properly to the subject sound and the microphone picks up extraneous sounds. The lens hood on many cameras further reduces the pickup of the source by hiding portions of the in camera mic. This Stereo Microphone solves these issues by having a more directional pickup and the mic is raised about the camera's lens hood. Recording quality is quite good and in-camera noises sometimes picked up by the internal mic are gone. Unit is for cameras with the Multi-show interface only. I do wish Sony made an adapter for older cameras (CX-760 for example) to use this unit securely attached to the camera. The mic also comes with an external cable to hook up the unit to a mic-in connection and comes with a nice carrying bag and mic wind noise reducer.
