Bring the audio in your videos to life with the ECM-HGZ1 shotgun microphone from Sony. Used with a compatible Handycam camcorder, the ECM-HGZ1 synchronizes the audio to the camcorder's zoom for audio that is distinct for both modes. In telephoto mode, the microphone focuses on the audio straight ahead of it, isolating the subject matter. In wide-angle mode, the microphone broadens is recording range, so no sound occurring in frame is missed. The ECM-HGZ1 is designed to work with your camcorder's Active Interface Shoe, so it is easy to connect and simple to use. It is powered by the camcorder, so there is no need for a separate battery.
