Hah - I have the identical set of primes except for the f/2.5 version of the 105 AIS. I also use the 180 when I travel, much less of a hassle than my old 70-200 f2.8 that's for sure. I also have the Sigma Art 35 (Thanks to Jack...:roll eyesSpot on, Jack. I use the 180 for travel. When a zoom is needed for sports etc., I have the 80-200 AF-S, which performs best @ f/4-5.6.
My current prime setup is:
Zeiss 21mm f/2.8 (excellent)
Nikkor 28mm f/2 AiS (mostly sufficient)
Nikkor 50mm f/1.2 AiS (very good)
Nikkor 105mm f/1.8 AiS (surprisingly good, even @ f/2.0)
Nikkor 180mm f/2.8 AF (what Jack said)
Nikkor 300mm f/4 AF (wonderful lens, but slow AF and not absolutely sharp @ f/4. will be replaced by a PF when monies allow)
You're in for a real treat with your D810, Lars. The guys here um, "convinced" me it was time to move up from my D700 and they were right. Only sorry I waited so long - it's a joy to use.
