The pick-up pattern of the built-in microphone on camcorders and DSLR cameras is omni-directional, meaning that it picks up all sounds in every direction equally, no matter which direction you point the camera. The SGM-990 is a 6" long directional, or "zoom" microphone with 2 switchable sound pick-up patterns, "Long" and "Short." Use "Long" to focus on your sound source or pick up sound from a distance. Use "Short" for when your sound source is close or covers a broader field. Both settings will provide rejection of unwanted sound from the sides and the back. The SGM-990 has a working range of 20-40 feet, uses 1 "AAA" battery, and comes with a windscreen and shoe mount microphone clip.
