Hi, Olympus E-M5 mk2, Pen-F, E-M1 mk2 do this with 8 shots, 1/2 pixel shifted:
http://andreas-wonisch.com/wp-content/uploads/2015/02/scheme_high_resolution_mode.jpg Olympus creates a 64MP raw file. I suppose it should be similar to their standard RAWs but you need a custom plugin to use it in CS5. DT opens it as a white image with random dots, while RT 4.2.0 opens it fine. You can find a sample here <http://www.imaging-resource.com/PRODS/olympus-e-m5-ii/olympus-e-m5-iiTECH2.HTM> . Some Hasselblad models do too (4 shots). Sony and Panasonic will be there soon (both have sensor shift).
