the noise is a problem because it can be heard in video playback, making it useless. i would like to know how people have solved this problem. i already purchased an external rode video microphone and attached it to the top of the camera - but unfortunately i also picks up the grinding sounds because it is close to the camera. i want to be able to shoot handheld without carrying another microphone or needing an additional person to carry a microphone. if there is someone who found a mic that works, tel me !
