Thanks for comments and link.
The feature seems to be a bit to restricting to be of great importance when making a new camera purchase.
In my case it would be only of use for landscapes on calm days and would require carrying a tripod all the time 'just in case'

Jeff,
Waiting for more test/reviews but it could be a nice system for me. I use a Canon 5D MK II + Sigma 50mm Macro for art reproduction jobs and use it too on travels. At least intended to do that as it happens more often that I take my son's old Olympus PL-1 with me + a Schneider Xenon C-mount. The reproduction quality of the Olympus OM-D E-M5 Mark II HR takes could be better than what i get with the 5D and I think the approach is sensible, the more as 4/3 sensors will meet the diffraction limits when they will get more MP. The sensor + lens optical combination is probably less challenged with this oversampling method than it will be in the new Canon 5DS (R) single shot system. When I read that Canon also had to improve moving parts etc for less vibration it rings a bell. I rather have controlled sensor shifts than unintended shifts :-) The best explanation of the 8 shot method suggests that the Olympus shifts 4x 1 pixel first so a true 16 MP R+G (+G)+B sampling is done (similar to Sigma sensor sampling) and on top 4x sampling between the first positions, so oversampling. Sensor has a weak anti-aliasing filter as I understand it. However the Olympus range should get a shorter (25-30mm) macro lens that can compete with for example the Sigma 70mm Macro lens quality.
There is an analogy with the Epson flatbed scanners that use oversampling, the sensor wells are larger than the pitch between them (several linear CCDs shifted half a pixel) and larger than the stepping rate in the scanner motion. At first sight that suggest an inflated resolution quote like so many scanner manufacturers utter but this oversampling creates a good base to reduce noise and by that increase the dynamic range in film scanning. With deconvolution sharpening one can actually create more resolution too than what can be expected of the sensor well size. I have done quite some work with wet mounting scans of films with both a Nikon 8000 MF scanner and an Epson V700 scanner, tweaked wet mount film holders, equalized focus fields etc. Often I prefer the V700 result.
Of course a Sony A7 IIIwith the same sensor shift could be champion next year.
Met vriendelijke groet, Ernst
