full frame with 4230x2820 pixels means the pixel size will be 8.5µm... it's huge... 70% more surface than the 5dmarkIII (6.5µm)...
if it's true it will be a low light killer
it's a pity Sony use XAVC S instead of XAVC... we will lose the 10 or 12bits, the 4:2:2... :-/
I suppose they don't want to encroach on their professionnal market
