I am starting this thread because I moved from a D90 to a D7000 in December and so far I am pretty pleased with the D7000's performance. But...there have been lots of complaints (real or not - see Thom Hogan on this) as well. Hot pixels, back focusing.
Being the amateur that I am I tried a lot of lenses to see how focus was. Did it back focus?
Yes, it seemed so, or did I leave VR on while on the tripod (I did).
In the end I couldn't really fault the D7000 (focus looks fine, but different lenses get slightly different results) and by now I am really enjoying the camera. Good ISO performance, even at 6400, very flexible menu options and a lot of improvements over the D90 I used previously.
In fact the D7000 cost me a lot of extra money, as it motivated me to get new lenses as well, to try out different possibilities.
For me this is a great new 'toy' so far.
Would like to hear from other users what their experiences have been so far.
I love the idea of the double card slot. Great improvement. I use the second card as backup, so one of my big worries that I always had going on holiday has disappeared it seems.
