I can vouch for the Nikkor 16-35vr and the Sigma 150mm macro, both are great lenses and I intend to put them to good use on my new D800. I also have a Tamron 90mm macro (my wife's) and it is a very sharp lens. My other lenses are 50mm 1.8D, 85mm 1.8D, 300mm AF-s F4 and my favorite the Nikkor 24-120vr F4. For walk around and street photography I don't think the 24-120F4 can be beat and even when IQ is critical, like on a model shoot, I have started to use the 24-120F4 over my primes.
