Hi I have D200 now and I'm planning on upgrading. What I'm not happy about with the D200 is high ISO performance and also I could use better auto-focus. My choices are pretty much D300, D700 and D7000. With D7000 I think I would get the high ISO performance I need (want). But is the af significantly better? Exposure bracketing is only 3 frames (maybe I could live with that). And I would have to get new memory cards and batteries. With D300(s) I would have the better af. I could use my extra batteries and CF cards. I would also have all the controls and features that I now have with D200. Also the buffer is way bigger than the one in D7000. But how much better is the high ISO performance? With the D700 I would get the better auto-focus, and high ISO performance plus all the controls and features I want and I would be able to use my batteries and CF cards. And thats the camera I want. But as always there is a but. I have some good (or at least decent) lenses, but most of theme DX. My zooms are sigma 10-20, 50-150/2.8 and nikkor 17-55/2.8. I also have couple of primes: nikkor 35/1.8, 50/1.4 af(non-D), 85/1.8 and 55/2.8 micro. If I went the D700 route, I would sell all three zooms and the D200, witch would hopefully get me enough money to buy the d700. Of course I would be left only with the 50 and 85. In addition I would get something wide, probably some wide prime or cheap zoom (like 18-35) at first and get better one later if needed. And then I would need also a tele zoom. Probably nikkor 70-300, 80-200 or sigma 70-200.And for the record photography is just a hobby for me. Here are some examples of what I shoot http://www.flickr.com/photos/tkaira/ Does this sound stupid? Would I be better of picking up one of the DX options? Thank you for any help!
