The D700 work as good as the D3 in a smaller size and lower speed. But still, with the Grip on, D700 still can shoot in 8fps which is as fast as my D2h.
Same sensor as the D3, which means, same ISO control too. I like to shoot in very high ISO, and without flash. Some times, i even push my D200 ISO to 2000.
This flash is surely the best. But price is even higher than the currently 580mk2. Lets wait till they both came out.
