I'm trying to decide on what second body (or first for that matter) to get. Either a D700 or D3 and I'm concerned about the smaller viewfinder coverage area on the D700 compared to my D300S and the D3. I rented a D700 for a shoot last week but didn't really pay any attention to it. Does anyone have any major issues with this? I'd consider a D600 but it's a little too small, slow, and I don't like the top 1/200 sync.
