The D3s is a fast beast. I have a D3 and I know that it is fast. So saying that the D800 is not as good as a D3s in this regard is not really a knock against the D800, especially since we knew that the D800 was not designed to be a sports camera to begin with. I wonder what Perrone would say about the D700 speed compared to the D3s?
The D700 is a great camera. And I don;t fault anyone for wanting to keep it in favor of D800. But if I were comparing the D700 to the D3s, I might be inclined to say that the D700 does compare well against it in terms of speed. A while back, I was shooting HS baseball with my D300 right next to a D700 shooter. And I was firing off shots with no abandon while the D700 shooter was having to time his shots more carefully. For these daylight shots, I am sure that mine were every bit as good as his, only I was able to get a few more shots that he wasn't. But I doubt the D700 shooter was trading his camera in for a D300.
