Cameras, though nearly always equipped with a built-in microphone, are for making pictures. If you want a decent audio track to match you need a real specialist of a microphone. Paramount are a reliable connection to or with the camera, be it wireless or mounted, and a robust design that doesn’t mind being pushed around. If there’s a Sennheiser logo on it you can be sure to get all that and terrific audio quality too.
Sennheiser has a long history in building microphones for broadcasting, so there are quite a few camera microphones to choose from. Depending on the area of use Sennheiser offers models that can be attached to the camera, used separately, or both. In any case your pictures will be accompanied by the sound they deserve.
