The Sony A7s is a high-sensitivity, full-frame mirrorless camera. It features a 12 megapixel sensor. Though smaller in size, there are less photodiodes on the actual sensor which makes it much more efficient in low light conditions.

The A7s features internal 1080p video and 4k via the HDMI port to an external recorder.

Introduced in April 2014, this is the first in the series of “s” branded A7 cameras.

I bought mine when it came out and I still use it today. It is somewhat specialized for low light and video, but its an excellent performer.
