Totally agree, some of my stuff also was purchased overseas, I think if Nikon are serious about making a global commitment to pro photographers then it shouldn't matter where your equipment has come from as long as you can provide proof of purchase…
Would have to agree with Brook on this one, 24-70 is just an outstanding lens on a full frame camera, not quite wide enough on my DX bodies for my work. The 50mm 1.4 is also great very good bang for your buck as they would say.
