i have the 70-200 VR I - Love it - would not trade this lens for any lens....
I also have the 28-70 - Love it as well, but it's not quite my "wow" lens like the 70-200..., I will keep it.
Next I want the upgrade to the 80-400... If it ever comes....
After that it's all primes for me. the first one I'm going to get, assuming the D 400 is DX, is the 35 1.8.
Please Nikon, I know you're going to announce a D400 DX, but what about upgrade to 80-400?
