Well the Eva is more production friendly and super 35 so that not really for the same audience .
But for my personal use, a camera with 4k 60fps , a good 4.2.2 codec, face detection continuous autofocus and low rolling shutter is everything I will ever need, So I think the next generation camera I will buy will last me much longer since I won t have to make much compromise anymore. Hopefully it will be a a7s3 .
I think we are lucky if we get 10bit 120p in FHD/2K, but if that's multi aspect I would have no reason to complain. 4K/60p/10bit internally would be badass but I doubt that, too much too soon after the original GH5. Owners would go nuts.
That advanced HDR sounds like a lot more reasonable and "prosumer friendly". They need to sell those HDR TVs somehow, showing off nature docs with over saturated colours and interpolated magic motion on the shopfloor won't cut it now.. they have to give you toys to create content with.
