Richard Payne posted a full GH4 review at Redsharknews and writes:
As I work for Holdan (a UK, Ireland and European Distributor) I see a LOT of professional camcorders and large sensor systems. In my 30 year’s experience of working with video cameras, I can say with hand on heart that the GH4 is the first camera I would trust for both stills and video.
Also Caleb Pike from Dslrvideoshooter reviewed the camera:
The Panasonic GH4 is an amazing camera. I haven’t been this excited about shooting since I bought my 7D. Not because its a nice toy, but because I can spend more time and energy on my projects, talent and cinematography and stop dealing with silly DSLR issues. Watch my review for the full lowdown.
