Had this bad boy for about a week. So far it's decent. Not a drastic change for the first version but there have been some useful upgrades. Pros: Internal 4k Better "feel" S-log3 works "better" with metabones adapter Memory card loads normally now better button customization s-log real feel display options (slog-3 is so flat that it's often hard to see) 240fps!! Cons: Battery life is terrible. Less than 30-45 minutes on a full charge It gets hot recording 4k 4k is a bit too compressed for my liking better if is was faster than 100 They have this stupid feature where the LCD screen goes black if you look through the viewfinder and vice versa. But on a sunny day it seems to cause only the viewfinder to work. Also you cannot make both work at the same time which is a pain because I would use the viewfinder to check focus and the lcd to check composition. Overall it's not bad, still not sure if I'd buy this one or just go with the FS5 and get all the features of a tdedicated video camer because the image quality of the A7s is just aweful.
