Sony A7S 4K video recording full frame mirrorless camera designed for both stills and video announced a few days ago. Here are some additional coverage from NAB Show 2014 for Sony A7s full frame mirrorless camera.
Sony A7s has been developed along the A7 and A7r cameras and the development took 2-3 years. The camera cannot record 4K internally because of power consumption and because of the heating produced by the large sensor.
The one big physical change compared to the Sony A7 and A7r is that the A7s has a stainless steel made mount. The Sony A7S features a new 12.2-megapixel with a 35mm full-frame sensor, 4K movie recording, ISO 50 to 102,400.
