The VideoMic from Rode is a shotgun microphone that can easily be mounted on a video camera or DSLR via its integrated shockmount that attaches to the camera's shoe. The VideoMic is lightweight, and when mounting on a camera it does not appear in the frame. Its super-cardioid polar pattern attenuates sounds from the sides. The result is a signal that sounds closer to the camera, even when shooting in noisy environments or at moderate distances. A 3/8" thread at the base of the shock mount allows you to use the VideoMic on any standard boompole. An attached, coiled cable terminates to a 1/8" (3.5mm) mini output connection. The VideoMic features a condenser element that utilizes a standard 9 Volt battery. The microphone will run for approximately 100 hours on a single battery.
