Holy CRAP. As I'm writing this, it's only been a day since Panasonic announced the full specification of the GH5, and it'll be another two or three months before it actually ships. But here's the thing. The GH5's specs exceed those of Canon's $6,000 1Dx Mk II and are actually more comparable to those of the $10,000 Sony FS7 II. Yes, there are differences, but let me repeat, holy CRAP: it's going to be awfully hard to justify cameras that cost three to five times as much, let alone cameras that cost just 50% more. You can see my first thoughts about it below.
