Just upgraded from D200 to D700. I'm thoroughly sick of the megapixel wars and believe that the D7000, although it is a great camera, is pushing it in that department (as one poster has already stated, needs excellent glass and technique to get the best out of it, not to mention that you can't go beyond F/8 without diffraction setting in).
I like my large pixels and great high ISO performance. Next purchase will be... a second D700 body.
Any ideas what I should do with the D200? I'm thinking infrared conversion.
