Sony has many imaging revolutions under its belt but the tech giant keeps pushing the envelope. It just introduced the industry's first 3-layer stacked CMOS image sensor. Plainly put, Sony added RAM to the image sensor to enable high-speed capture - like 1080p video at 1,000fps, for example. The camera actually captures two streams - one at 1,000fps and one at regular speed, both of which are stored in the on-chip RAM for later processing. This allows the camera to integrate slow-motion segments into regular speed videos seamlessly. Don't worry if you don't have lightning-fast reflexes...
