What are people using to hook up their GH4 for audio? I need to be able to shoot video and have a mic attachment that will give me good audio. I will use Lavalier mics and I am hoping a handheld mic for interviews. I have a Beachtek hookup that I used in the past but it seems to bulky for street interviews that I am doing. I am looking perhaps for an offboard digital mic deck? Any help or recommendations greatly appreciated.
