Just like Lytro camera (see example video here) or like recently announced HTC M8 smartphone (working principle) Panasonic may also announce a M4/3 camera in upcoming year with Shoot First, Focus Later technology.
Latest patent litterateur shows that a new sensor with two layers of photosensitive cells, we don’t know the real tech behind this, since it is difficult to cover the total depth of image plane with just to active photo sensitive layers, but we hope that may see a real M4/3 Shoot First, Focus Later camera in next 1 to 2 year from Panasonic.
