I did an evaluation of ZD Camera vs D800E, both with prime lenses (Nikon 50mm F1.4D, Sigma 70mm F2.8 and Mamiya AF 80mm F2.8, at sharpest apertures) @studio.
ZD seems to have a higher level of pixel sharpness and appears to be better enlargeable.
D800E gives a larger file from the start but I could not get that tight crispness of ZD yet, although still pretty sharp.
ZD is much more prone to moire than D800E, considering similar image composition and the same subject & light.
D800E does not handle overexposure well, its strength is in the shadows.
D800E shadows are NOT noise free, even at ISO 100 there is a fine noise with grain structure. Although it depends on how deep one chooses to look into these shadows.
ZD's strength is in highlights, it handles even 2EV overexposure but shadows are not to be lifted much.
