The GH5, GH5S, and now, lo and behold, the GH5 Mark II have the "awfullest" autofocus on the planet. Why is there a major, picture busting performance difference between AF when shooting stills and AF video? AF video is unusable PERIOD; it happily stays unfocussed forever. I've missed more shots in bright sunlight than I care to remember and often flip to stills just get something. The ONLY thing that keeps me with the camera is it's 4/3 and I can't afford money or weight for the real AFers (and it appears no 4/3 can handle AF consistently, repeatedly, and reliably). If anything, the AF is overrated unless we are focused (pun fully intended) on stills only. If someone has a magic bean for GH5 AF video, I'll eat the electrons of this post.

No, 4K is not worth it. In fact, digital projection is a disaster and I believe the only reason the movie industry gets away with such inferior quality is because people don't care about it and, of course, there's no competition to the media. Every movie I've seen -including Skyfall - at AMC which blasts its Sony 4K notification at the start - suffers from color loss, brightness loss and poor dynamic range (Xiong's bulb turned down??). I do far better on my cheap Mits projection screen with an old Cinemascope production (viewing distance??). There's a reason why this particular form of entertainment is - or was - called the dream factory and that's because the medium's "limitations" were a way to present a story that, even in its most "realistic" tone, still had a dreamy, not of the day-to-day reality quality. That is simply not there with digital anything because neither of the ???'s or any of the new limitations, were an issue "back in the day". Without significant change in this current situation, the digital madness at theatres will only accelerate the advent of the home theatre as more people finally realize that the price they're paying for non-quality isn't a value proposition. And, with an aging population, that's a more serious problem that it might seem.

Nice review with much information. Definitely looking forward to the GH3 comparison. One note: review had a bit too much appleness in it which consequently left it less than platform agnostic.
