Here is my problem: I have a D3 with 14-24 2.8, 35-70 2.8, 70-200 VR and 300mm F4, and I am extremely happy with all of them. BUT I am a 65 year old short fat guy with a bit of a heart condition and like to go away for short photographic trips to various European destinations. Next month, Copenhagen. I will take the D3, the 35-70 and perhaps the 14-24. There is no way I could contemplate carrying the 70-200VR as well. But I miss the reach of a longer lens. I like to shoot candids and some architectural detail. I have briefly considered a Tamron 28-300, but I am being drawn more and more to the 70-300VR. So my question is: would the 70-300 VR be a total quality mis-match on a D3 or will it solve this problem for me?
