I shoot 2 D300 ( how do you indicate multiple D300 without saying D300s??) with 17-55 f/2.8 and 80-200 f/2.8. and I need the 10 pin connector for the remote release. I feel abandoned by Nikon. I have (had) the top of the line DX and it was considered the semi-pro. Now to maintain competitiveness with other shooters, it looks like I will have to sell all my gear and start over with FX. The specs on the 7100 look good compared to the 300/300s and would be good for shooting weddings but already some are specifying second shooters must be 700/800 or 3/4 Nikons. No more D300 and the 7000 is not good enough.
Nikonians is the Smithsonian of Nikon knowledge. If there is a question they can't answer, I want to see the question.
