Actually a some measurement sites say D7000 has higher dynamic range. I have tested both before and I think the dynamic range is very similar. maybe D7000 is a bit better.
Interesting to know that. In that case i'm very keen to know what the new replacement model for D300s has to offer! I'm not saying D700/D800 is not as good. It's just that when I'm shooting motor sports, 1.5x crop factor does a greater deal for me than an FF body.
