I played with D800 and a shaved 10.5 nikkor

D800 pixel density (wonder why Dpreview dropped the good habit to give the
value!) is 207 pxel/mm The 10.5 was projected with hires APSC in mind, and
gives stunning results on a D7000, 16megapixel APSC (DX), that has 211
pixels/mm.
Line/mm performance in optic is going radial geometrical law (the more
distance from the center, the more the lines/mm that are resolved,
decrease) and is depending on aperture too.
I'm SURE that 10.5 used at f6.3-f8, as usual for panoramas will be able to
handle even the new D3200 at 24megapixel APSC.
I'm even sure enough the 16mm 2.8 Nikkor is good enough for the D800, and
ebven more sure that the incredibly good 15mm 2.8 Sigma will.
I've doubts about Tokina 10-17 and Sigma 10mm, both just a bit under the
line.
Any use of the 8mm 3.5 Sigma would waste a lot of panos resolution in black
pixels
