Dan Watson posted this full video review and GH5 article on Huffingtonpost:
It really is a revolution for compact video cameras in a way that cannot be overstated. This powerful camera takes filmmaking seriously and any filmmaker should take the GH5 seriously. While every other camera in this market, including the Sony A7SII and 5D Mark IV, comes with required workarounds to integrate them into your workflow, the Panasonic GH5 feels like it was created to fill all possible needs. Sure, it’s no A7SII in low light mostly due to the smaller sensor, but with an articulating touch screen, better ergonomics, amazing customization, 4k @ 60p, crazy slow motion, unlimited recording, dual card slots, better battery life, 10 bit video, and so much more, you should really consider how important it is to shoot at 25,000 ISO. For me, the Panasonic GH5 is the camera I was waiting for, well worth the $1,999 price tag, and flexible enough to navigate through a professional video shoot while still being compact enough for me to carry it unnoticed in a small bag on a trip to Disney World.
