[QUOTE have you shot 8-9 hours with a 70-200 VR on the D7000? if so, then you are different physically. Bravo to you! i need the bigger body when i shoot for long hours.
...and let me add AGAIN, the D7000 is a great camera[/QUOTE]
Yes I have shot 8 hours with the 70-200 on my D7000.
I find it balances just fine with one hand on the zoom ring and the other on the camera.
It is a lot easier for me than the much bigger and heavier D3.
