The resolution chart page is predictive of what me might see on a flat (planar) outdoor subject. This page confirms those findings.
Images taken on the 24.4MP Nikon D3x. The resolution of the D3x on an as-designed-for 55 X 55mm film/sensor area is equivalent to a 58 megapixel image; covering an area of that size is a serious optical challenge. Field curvature is one area in which design constraints are often relaxed.
With the shift capability, one can reasonably expect to photograph architecture with the Hartblei lenses.

Therefore, this image is quite within the scope of reasonable use.
