Some of the interesting tidbits:
– A7s has been developed along the A7 and A7r cameras
– development took 2-3 years
– Reason why the camera doesn’t record 4K internally is because of power consumption and because of the heating produced by the large sensor
– The one big physical change compared ot th A7-A7r is that the A7s has a stainless steel made mount.
A7s sites in different languages at Sony US, DE, UK, ES, FR, IT, NL, SE, FI, PL.
