Interesting comparisons. I see a small but noticeable improvement in detail in Image 3 compared with image 1.
If I recall correctly, Ricoh's implementation of pixel shift produces images with the same pixel dimensions as a 'normal' image but with increased detail. This contrasts with the Olympus implementation which produces images about 4 times (in area) that of the 'normal' file. I just bought an E-M5 MkII but I'm yet to test its pixel shift capability. I'm not sure it's something I'd use often anyway.
