Take aways...
Best IBIS of all FF - 8 stops RF and 6 stops EF adapted
DR is on par with Sonys best
ISO is again one of the best
Overheats internally with high quality 4k and 8k, Atomos external will give over an hour with no overheat warning
Fast sensor readout electronic shutter
64GB CFexpress RAW 8K = 3min recording time
30min recording per clip
Dual pixel II looks impressive
Rolling shutter decent
IMO the 24-105 looks really good judging by the samples, renders a nice image
I guess if you want longer video clips at the highest quality then you get an Atomos or you buy an A7siii (also some reports of overheating, wait and see suppose).
