I've been using the Zeiss Hasselblad V lenses with the D800e, with a Fotodiox adapter. Focus confirmation works, just remember that the arrows point in the opposite direction as the V lenses focus ring moves in the opposite direction of nikon. The 80 CF, 150 CF, 50 C, 120 CF and 180 CF are outstanding. The 80 and 150 are my two favrite portrait lenses on the D800e, and film for that matter.
I have a 60 AFd Micro and it one of the sharpest lenses I've ever used.
Have fun! The D800 hits on so many levels, with only a few draw backs. I wish the VF were bigger, and I wish you could change screens. other than that, it essentially replaced (not entirely) MF digital, Leica M and Mamiya 7.
