The VideoMic GO On-Camera Shotgun Microphone from Rode is a lightweight microphone which adds high-quality audio recording to your small camcorder and HDSLR camera. At only 2.6 ounces, the microphone keeps your camera setup lightweight, making it ideal for handheld shooting. It features an integrated Rycote Lyre shock mount for isolation from bumps and vibration, and offers battery-free operation, using instead the plug-in power from your camera's 3.5mm microphone input. Please note that the microphone will not work with cameras that don't supply plug-in power to their 3.5mm audio input jack.
