Ah, thanks! That helps me understand what others refer to.
I had never handled either a D3 or a D300, so I don't know how those compare. Before I bought my D70 four years ago, it was a bit of a shock comparing the touch and feel and handling of that with that of my Nikon F4, which has such a solid, quality feel about it.
I've had my D700 for just a few days now, and I'm very happy with it. It's umpteen times much better than my D70 in every way. But the D700 does fall short of the handling and feel of my F4. Perhaps the F4 is somewhat similar to the D3??
