What’s the main feature that makes the Sony Alpha A7s camera so impressive? That it can shoot 4K quality video (four times that the traditional 1080p HD mark) at a maximum ISO range of 50 to 409,600 — that’s well past dark lighting scenarios, which makes for an excellent camera in almost any situation.

In order to make the camera more sensitive to light, the sensor size had to be reduced, so the Alpha A7s only takes photos at 12.2 megapixels. Since it is more technologically-advanced than its cousin, the Alpha A7 which costs $1,999, except the Alpha A7s to cost more than that.
Put your money where your mouth is, Sony.
