I believe that one of the primary purposes of this lens design is to minimize coma (from Nikon's press release: "top-class low-light performance is ensured with minimal sagittal coma"). Do any of the DxOMark tests measure performance in this regard? If not, are we ignoring an important aspect of this lens's intended quality? With digital photography, it is much harder (if not impossible) to correct for coma than it is for than vignetting or chromatic aberration, so giving so much weight to these latter categories seems misplaced.

Thanks for your comment.

Coma is not measured on
In fact, this aspect is partially assessed with sharpness measurement and chromatic aberration. The main weakness for the Nikon 58mm f/1.4 is sharpness for wider aperture.
