Well I think AF on panasonic lumix camera's is decent. Face recognition and autofocus works fine 99% of the time.

How interested are you in a GH6 anymore?

Good AF is all or nothing - either it works (ie - is dependable), or it is not.
What Panasonic's Depth-From-Defocus system offers instead is continuous auto-focus - i.e. a system that maintains focus as the user smoothly pans across a wide range of scenery. Lightweight Lumix prime lenses are particularly well-optimized for this purpose - their miniature internal focus mechanisms respond far more quickly and seamlessly than massive full-frame primes and zooms.

But why would you use AF for panning - especially from a static position - unless there are various objects spread out across the focal plane. I'd imagine you can use push-AF to lock focus and then pan.
Panasonic AF is extremely inferior, no matter which lenses are used.
And not sure which full-frame lenses and zooms you have experience with, but many Sony and Canon lenses are excellent.

The main problem with Panasonic AF in semi recent models is that it loses it way. It is fast enough and accurate enough for many situations. It is just that for no reason it will adjust the make visible out of focus movements until it dials in again. This is unacceptable for "work". I can't understand why they can not fix or improve this outside of DLD's cartel theory. But, remember how the internet had to tell Panasonic about the 24p/60p AF difference in the GH5? That was pretty scary imho. So maybe they are at their AF limit?

Legalistically, cartels are below the belt in the US and the EU ... unless it's OPEC. Then it's OK. They are allowed to live long and prosper in Japan and Korea. Panasonic, Olympus, Nikon and Fuji buy their sensors - MFT, APS-C, FF and MF - from Sony, something that would be frowned upon by the anti-trust authorities in a market with so few participants. It makes no difference to the same authorities if Toyota buys its engines from BMW or that Supra is a rebadged Z4 because there are so many competitors in that biz. Additionally, Panasonic, Olympus, Nikon and Fuji get an inferior performance in AF from the same sensors, though Sony plays its own cripple-hammer by limiting its sensors pixel-shifting performances. In a competitive market, there'd be more vendors or more in-house sensor development that would result in a constant leap-frogging of one company over another.
And, the reason I posted a YouTube link to that Lidar based AF system is because it could potentially serve as a major market disruptor since it could eliminate the proprietary lens mounting/ecosystem as a major determining factor. It could also bring a lot of smaller manufacturers of the manual cameras and lenses back to importance and cause a few tremors to the aforementioned cartel.

You would tend to think Panasonic could have better AF, but either can't afford to license it, or are not allowed to.
All AF misses sometimes, but Panny not only manages to miss shots every other system would consistently hit, it pulses like mad while doing so.
That pulsing is actually far more an issue to my eye - once pointed out, you always notice it. The new firmware is better at reducing it, but it's still there.
Unpredictability is also rarely mentioned, but also a huge issue. With the exact same settings you'll get wildly different results in similar lighting conditions. I've had the AF working fine, turn off the GH5, then have it behave differently. It's very bizarre.
Their system just doesn't work, and considering R&D budgets will be going down, it likely never will... unless they make the switch.John Vincent

I stuck with the GH2 through 4 and AF100 for many years. I always enjoyed the size and capabilities of the m43 system.
I hated the relative expense of the lenses vs. Panasonic's absolute refusal to make them durable or repairable, and piss-poor low light performance.

I just took a look at the Blackmagic Pocket Cinema Camera, which comes in two versions: a 4K version that uses Micro Four-Thirds lenses and a 6K full-frame version that uses bigger lenses. The 4K version costs $1300, which includes the paid version of DaVinci Resolve (which costs $300 if you buy it). The one time I tried a Blackmagic camera with my Panasonic lenses, the camera and lenses did not talk to each other at all -- everything was completely manual, and my recollection is that even switched to manual focus, I could not focus the lens.
Otherwise, the writeup on Blackmagic's site makes the Pocket Cinema Camera sound like it walks on water. One noteworthy downside (compared to the GH5) is that the 4K Pocket Cinema Camera takes stills at 8.8-megapixel resolution. (The 6K version takes 21-megapixel stills.) But it's clear that the Pocket Cinema Camera is built for video, not stills. If funds were unlimited, I might think about getting a Pocket Cinema Camera and a non-Panasonic lens or two to augment my GH5.

MFT system is the most widely/broadly supported mount ecosystem out of all the mirrorless. It is still going strong.
Look at how the GH5 is still very strongly relevant as professional workhorse even now in 2020 years after its release!
The GH5 even now still has features that very few of its competitors have, or even none of them! Or simply don't do them just as well.
The IBIS in a G9/GH5 is still one of the very best there is.
Who else has waveforms? Nobody.
Who has the rock solid reliability of the GH series? Nobody.
Who has anamorphic modes? Very few.
Who has full size HDMI? Very few.
Who has anything similar to DMW-XLR1? Just Sony.
etc etc etc
This list could go on and on!
It will be worthwhile waiting for the Panasonic GH6.Am a Sound Recordist in New Zealand: http://ironfilm.co.nz/sound/

Apparently the Panasonic imaging director said the GH6 was in development and to "stay tuned" in a an interview. https://www.diyphotography.net/stay-...gh6-is-coming/
Imho, it would be best sooner than later...
