I'm in a bit of a quandary. I have a m4/3 kit based around an EM1 mki, EM10, and EP5 with the Olympus f2.8 zooms and 4 nice primes. At this stage I'm looking to get more into video - i already shoot quite a bit - and so I want a more video capable camera with 4K. The EM1 mkii would be nice but doesn't have all the video functions I need so consequently I'm looking at the GH5. My question is the Panasonic DFD focus is based only upon Panasonic lens profiles so if I get a GH5 will using my Olympus lenses mean decreased AF performance and so will I need to start acquiring Panasonic lenses as well?

The DFD will work better with Panasonic lenses, and yes, a full profile will realize the full benefit. However, as the Japanese GX850 brochure states, there's a partial DFD benefit even using non-Panasonic lenses (which does include Olympus lenses).

I can say that my GX850 focuses better than my OMD EM5 MKII, Pen-F. Even the GM5 without DFD focuses better than those. But the EM1 MKII represents a major performance jump for Olympus...

My take honestly is- if you need video and by that I mean serious video, go for the GH5. It will still focus very fast with whatever lenses.

If you need ultimate speed/AF performance, but just pretty good video, go with the Olympus.

Honestly I think more than the AF, the first question is how serious you need/are into video. The GH5 may be overkill - or not.

What I can say though is that none of my Olympuses focus the Panasonic pancake F1.7 MKII which I adore accurate on most situations when it should, while the Panasonic bodies do.

My EM1.1 focusses the 20mm f/1.7 mk1 fine. Never had missed focus. Noisy and a bit slow but accurate.

That's great and one would expect that from a camera that has phase detection. But the other Olympus models don't fare as well. I certainly expect the EM1 MKII to do much better here than any previous Olympus model.

Supposedly the EM1 only uses PDAF with MFT lenses in CAF.  Who knows.
