4K has securely replaced 3D as the buzzword feature on new TVs, and as content producers scramble to churn out genuine ultra HD content, it looks like Sony's new A7s just might be their weapon of choice. It trades the 36.4 megapixels of the A7R for a 12.2 megapixel sensor optimized to shoot incredible low-light video in the darkest of conditions.

For comparison, the Sony A7 and A7R top out at a max ISO setting of 25,600. Where as the new A7S boasts a max ISO setting of 409,600. And this stunning test footage, shot by YouTuber Yoshihiro Enatsu in the dark of night, only pushed the camera to between ISO 8,000 to 40,000 without a speck of visible noise. Are we sure Sony isn't just cramming a pair of owl eyes into every one of these cameras? [YouTube via Stu Maschwitz (Twitter)]
