Although Nikon has demonstrated fairly good on-sensor PDAF performance in the Nikon 1 series, apparently some of the inaccuracy is hidden in the deeper DOF of the smaller sensor format.
Some other manufacturers (mainly Sony IIRC) are doing a final CDAF adjustment step after initial acquisition with on-sensor PDAF which slows down the overall performance but Nikon's F-mount lenses are supposedly not optimised for the this.
So whilst many of the focal lengths are covered, the lenses may not perform as well in a mirrorless setup.
If this was the case, who would buy a mirrorless F-mount over a DSLR F-mount?
