Olympus E-M5 Mark II has a new 40 Megapixel High Resolution Shot mode (7296x5472 pixels).
During the capture process, the sensor is repositioned eight times around a square. It takes the first shot, shifts right by half a pixel, takes the second, then right again by half a pixel for the third. Then up half a pixel for the fourth, up another half for the fifth, then left by half a pixel for the sixth, left half again for the seventh, then finally down by half a pixel for the eight and final shot.
The 40Mpx mode switches the camera to an electronic shutter and fires its eight shots in just under a second. It then takes about two and a half seconds longer to generate the final composite file. Understandably the camera and subject should be kept still during the capture process (moving subjects - cars, people or birds - typically appear as eight faint shapes next to each other).
The maximum exposure (per frame) is eight seconds and the highest sensitivity is 1600 ISO and the minimum aperture is f8. You need a good tripod or something very stable.
