One particular case where detail is most likely to be lost in 'M' 6MP size, is where 'EXR-DR' is deployed at low ISO - where it appears that the 'dual exposure time' process may result in half the sensor pixels simply being discarded entirely (not even 'binned'). This not only limits the resolution due to the lower MP count, but can also introduce increased aliasing artifacts (jaggies, moire patterns etc) due to the much lower '50% fill-factor' (under-sampling), and it actually also results in the image noise being closer to that of a 1EV higher ISO setting because there is 50% less pixel/noise averaging comprising the final image.

Thanks Mark, yes, that's exactly what I was seeing. So is 'M' EXR-DR doing the same processing as 'M' (Aperture Priority) DR400% ??
