Hey all, I recently purchased the panasonic g7 kit from Adorama which had a "free" Audio-Technica AT8024 microphone. It all works well with the kit equipment but when I attach my panasonic 12-35 2.8, I pick up the autofocus noise on the shotgun mic. I found it strange because the 12-35 was noticeably quieter than the kit lens and had concluded that it might be because the physical size of the 12-35 extends closer towards the end of the microphone. Moving the mic a few inches away seems to resolve the issue somewhat so I figured I would pick up something like this: Vello Multi-Function Ball Head with Removable Top & CS-BH1 However, before I do, I had two questions: 1.)Is this behavior normal, because I can still return the mic if not. 2.)If it is normal, do I have the right solution?
