The Sony ECM-GZ1M Zoom Microphone is a monaural on-camera microphone
that features a hot shoe interface specifically for Sony cameras and
camcorders that have the propriety Multi-Interface Shoe. The microphone
is designed to help isolate the sound you want originating from the
subject while rejecting unwanted ambient noise. It offers two setting to
choose from: a "Gun" Mode which locks the microphone in a fixed pick-up
pattern, and a "Zoom" Mode which dynamically adjusts the pick-up pattern
in relation how much you zoom in, making the microphone pick-up angle
narrower as you zoom closer - Zoom Mode requires a camera or camcorder
with a zoom lens.
