Yes there's something very satisfying about getting this level of pixel-level quality - reminds me of the satisfaction of seeing sharp details emerging through the grain of film. Trouble is, the difference between the pixel-shifted and normal exposures from the same camera is such that once used, I think many of us may not want to go back to the bad old days of bayer interpolation. Sigma may do well out of this! After this I'm expecting the DNGs to be phenomenal.
So if the DNG files are nearly 4x the size of normal DNGs, I take it we are looking at files which store all the luminance data from four captures, which is subsequently demosaiced in PP, rather than the demosaicing happening in-camera and a file output with full colour data at each pixel? I was hoping for the latter, but I'm not complaining.
