Came back to this thread because, now that I've been using the D5100 for a few months, and re-acquiring some of my lost lenses and acquiring and using more (having great fun doing it all), plus brushing up on my old, but a bit outdated, skills, and learning more - here, in particular - I'm now wishing that I had some of what the D7000 offers. More detailed focus options, two card slots, weather-proofing, a more rugged build, are a few - also, more shutter speed options.
Am I nuts? Is this just our old friend NAS talking? Or, does this make sense for a fairly advanced amateur who now realizes that the D5100 may be not be a sufficiently advanced camera for me and my skill level? I note that one poster in this thread said they were using their D5100 now as backup since acquiring a D7000 - I've been using my aged, but still perfect, D70 (all 6 MP of it) for that. Now, I could have two serviceable backup bodies, and I do appreciate the size of the D5100.
Should I wait to see what other DX bodies Nikon comes up with this year, just wait and see if this makes sense, or what?
