Hi guys,
I've been a lurker in the forums for quite some time now, but this is my initial post.
I received my GH4 yesterday and have been playing with different setups. This is the best so far. Regular shoulder-rig with cage. A Røde shotgun mic with pistol grip attached to a super clamp which is attached to the cage. Sounds like a bad idea, but works wonderfully, and are easy to detach. There is no wiggle or instability. The Røde is connected to the Zoom H4N which is connected to the Panasonic. I've had great results so far with my testing and its hard to tell the difference between the GH4 Audio and the H4N recording. You can of course record audio with the recorder and have great referance audio in the GH4.
Works really good when you don't have a designated audio-guy.
