The French startup Pixii has announced its first product and it's ambitious. The Pixii camera is a digital rangefinder that accepts Leica's M-mount lenses. Unlike a typical digital camera, however, it ditches the built-in display and replaces it with the screen of your smartphone. You compose images through an optical viewfinder and, when you fire the shutter, the camera saves the picture to internal storage (which is available as 8 or 32 GB). There's no SD card, instead images transfer to your phone via Wi-Fi.
