Why no focus issues with D5100 or D3100 compared with D7000

My D5100 has sporadic focus issues

I chalk it up to a limitation of using zoom lenses with PDAF to be honest.... there is a reason AF Micro adjust features on higher end DSLR's (Which I used successfully on my D7000, D300 and 5D2).

Lens rentals had a very informative blog entry on this some time back.

My 16-85 struggles at certain focal lengths so I find myself using live view at 85mm for example. Speaking with the Nikon service agents, the combo could only be optimised (at cost) for one focal length on a zoom.

Its not terrible, but something to think about for critical work.

One of the many reasons I'm looking to go full mirrorless in the future.

Otherwise, for those who need DSLR's, Canons new approach for putting microchips in high end optics with data pertaining to that specific copy seems to be a good (albeit expensive) approach.
