Looking for a shotgun mic to connect to your camera that will work with a battery? The Saramonic CamMic+ is a great option and will record clear audio rejecting back noise.
It has an 80 Hz low-cut filter which improves the sound quality and helps remove low-end rumble and background noise.
It comes with an integrated shockmount that will reject handling noise and includes a windscreen to protect against wind noise and will also protect it from weather and dust.
