Hi Phil. I think everyone has their favourite lens and it is dependent on their style of photography I suspect. So basically depending on what you are shooting that narrows down the lens that is "perfect" for that. I love my 14-24 on my D800 for landscape. But I love my 85mm f/1.4 for portrait stuff. I also love my 50mm f/1.4 for the same thing. when shooting birds I can not go past my 150-500mm sigma OS lens. so basically depends. I think all decent lenses are pretty good no for the D800. I am sure you will get a lot of feedback on this topic. should be interesting.
