This lens performs modest on these type of test because Nikon designed NOT to do well.58/1.4G designer Haruo Sato expects such result, stating that aberration is controlled to have smooth background bokeh at close distance instead of persuing sharpness. The lens is uniquely designed to have different character depending on subject distance, with more sharpness at infinite and less so (with pleasant bokeh) as getting closer. Sato says those character remains unless shooting at smaller aperture such as f/8 or f/11.
Shooting test chart at infinite distance might show different results :-)
