Finally rented one from BorrowLens for a week. Though I had it long enough, I just didn’t get to play with it as much as I would have wanted to 😦 I took it out just once, but most of the time ended up being in the Arbor Theater watching “The Theory of Everything“.
I have borrowed / rented the D700 a few times (from both a friend of mine and also from Precision).
Nikon Just came out with a FX Format D700 (announced July 2, to be made generally available late July / early August).
Ken Rockwell has a comparative review of the D700 vs the D3 and Canon’s 5D.
