That is pretty cool. Why don't they have spotting scopes (at least) using that technology?
Right now, it is newly developed proprietary technology from SONY. The big player in cameras is Nikon, then Canon, and then a distant third is SONY. The last 10 years, SONY has been really developing their camera technology in hopes to become a serious player in the camera market. Their Technology is top notch, and NIKON is even using a Sony sensor in some of their DSLR cameras. There lenses are where they are lacking. However, photographers are the biggest "fan boys" in the world, and arcially.
The mirrorless camera technology drastically reduces the weight and size of a professional interchangeable lens camera, so I am certain everyone will try to replicate or surpass the technology eventually. Those A7s will even sync with the internet to upload pictures straight to the net. Pro wedding photographers were tired of getting sniped at weddings since everyone has camera phones now. e die hard brand guys. Plus, each brand of camera uses a certain lens mount. So if you have thousands invested in lens for canon, buying a new Sony or Nikon wouldn't be a good move financially.
By the way, it isn't really "night vision" the camera just has a SUPER high ISO setting.
