Wonderful !!!!
I ended with an A7SII... I love it for its dynamic range and convenient aspects like small size, USB charging, 24x36mm look. In some ways i don't like it : 8 bits luma, color that have to be adjusted very well depending on lights sources, and the major drawback, the rolling shutter that sucks a lot...
I've used it in replacement of some big cameras on some shots for commercials i make, and it is truly a good camera to my eyes... But clients don't want small photocams like this and i still rent the big brothers i'm used to.
This FS5 looks like it's a cool camera... I'm waiting the RAW update to see if it does like the FS7, where the benefit is not a big big step... We'll see !!!!
