D800/D800E Technical Guide
is available for download at:
Some interesting stuff in there about apertures, diffraction, moire etc.
'The D800E is a good choice when you need high-resolution photos of visually complex subjects.'
You ideally need to get both bodies then!
Re: D800/D800E Technical Guide
Can one assum that they will publish the diffraction limits on each lens when used on the D800E ie what f stop to avoid? Or how small you can go before diffraction?
If they release a 48MP D4x they will have give the same info on that body as well.
Might still be ok at f8 on the same lens. Pixel count would only be up by 1/3.
