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+i has a working range of 20-40 feet, uses 1 “AAA”
battery, and comes with a windscreen, shoe mount and hook-and-loop
The SGM-990+i also includes a mobile device interface cable to make it compatible with Smart Phones and Tablets, as well as DSLRs and Video Cameras.
