Interchangeable lenses and Android 4.1. If that wasn’t enough to be an innovator, now we know that Polaroid’s (oddly named) iM1836 camera has the sensor built into the lens (it’s a 1″ sensor). Though this was done in the past by Ricoh (with the GXR). Moreover, Polaroid says that there will be adapter modules that can take Nikon F, Pentax K and Micro Four Thirds lenses. If I got it right than the camera itself has no sensor and the sensor will fit within the Micro Four Thirds adapter.
