My copy arrived on thursday.
a few & quick impressions:
1) As it is a f1.4 lens. AF accuracy is good on my D5 (center AF field and AF fields at the edge work properly). Needed no adjustment
2) Different than the AFS 58mm/1.4 at open aperture - more sharpness
3) lens is not only for portraits, nice 3-d pop effect at larger distances
4) less LoCA at open aperture than the AFS 85mm/1.4
Will take more shots over the weekend. Enclosed a few initial images. all at f1.4. Just resized, no pp.
