OK. I just need advice. I have a D300 and a D40 - both fairly new. I want something better than the D40 as my 2nd camera. I have a decent collection of lenses already (85 1.4, 50 1.4, 28-70 2.8, 70-200 2.8, 35 1.8, etc). I don't care about video capabilities at all. I am not a pro, just an amateur. I seem to shoot a lot of low light situations without flash (gigs, churches, etc). Very good ISO and low-light performance are key. Pixel quality is vital - I love taking sharp photos. I have about $1500 to spend. What should I buy? A slightly used D7000 or a used D700 or D2 or another D300 - or just pay the big extra and get a used D3? I'm open to getting something better than my D300 if my price range is open to that. I've never shot with FX so I have no preference if I'm DX or FX right now. What should I buy? Here below is recent photo I took at church using my D300 and a new Sigma 85 1.4. This is typical of the type of photos I've been taking & would like another camera to improve or complement this.
