Sony's Action Cam is now no longer a prototype. The supercompact camcorder measures 2 inches high by 2.6 inches deep by 0.9 inch wide. you'll find Carl Zeiss optics and behind that are a 16-megapixel Exmor R BSI CMOS sensor and a Bionz processor. You get five MP4 recording options: 1080p30, 720p120 (for 4x slow-motion capture), 720p60 (for 2x slow-motion capture), 720p30, and 480p30. The camera has digital image stabilization and can also do time-lapse photography and shoot 16-megapixel stills. The camera has no built-in storage, but it has a card slot supporting both microSD and Memory Stick Micro cards. It has a removable battery so you can carry spares and charge by Micro-USB. There's also a Micro-HDMI output so you can review your videos on a big screen. There are two versions: one with built-in Wi-Fi, one without. The wireless connectivity will allow you to send clips to iOS or Android devices as well as control the camera's settings and use your device's screen as a viewfinder.
The Sony Action Cam ships in September and will sell for about $200. If you want Wi-Fi it'll set you back an additional $70.
