How is the low light in the gh5 compared to the gh4 btw? Maybe better asked in the gh5 thread..
I'm running the GH5 on autoISO (so I can set the shutter and aperture) and got it set to max of 6400. Inside FCPX when I'm cutting it all together, I can't tell what the iso the camera picks (which is bit annoying) but so fair I've not questioned the quality of the footage - really feel it is a big step up from the GH4, but saying that I was never really disappointed in the GH4 either.
