Canon DM-E1 External Directional Microphone offers enhanced audio quality as well as greater recording control to render more dynamic video productions - Shotgun and Stereo directional controls can be easily adjusted using the directivity switch. This microphone is compatible with select EOS digital cameras that have a dedicated movie recording mode and an external mic jack - A frequency range of 50 Hz to 16 kHz can accurately capture a wide variety of sounds, including live music and dialogues. The included wind screen helps to reduce peripheral sound from wind or other ambient sounds for cleaner, more focused playback - Additionally, the microphone has an integrated shock mount construction to reduce camera and lens operation noise. This microphone incorporates its own power source to offer longer continuous recording times - A power check lamp is featured on the mic body for checking battery level status, and it turns on or off in conjunction with the camera's own on/off switch.
