I am new here and thought I would ask for an advice. I am switching from Canon system to Nikon. I am looking to buy a camera body and am just torn between the choices. The budget is under $2000 or so, give or take. But I am trying to spend less if I can find a way that meets my needs. I have a 4 year old kid that I shot a lot of photos of, and he is constantly on the move. I also liker portraits, and do occasional nature shots. I have already acquired the following lenses: Tokina 28-70 2.8; Nikkor 50 1.8, and older Nikkor 70-210 3,5-5.6 I would love to get the D700, but it is on the more expensive side of my range and I am not sure I would enjoy carrying it, as it is quite weighty and substantial. I have large hands and therefore, find small grips very uncomfortable. I could just buy a DX camera, but do not want to loose the wide angle with the DX camera, even though I am open to investing into another lens that would give me the equivalent of 28mm. unless I find a cheap lens that is a great value due to its optical quality. I know Ken Rockwell raves about the cheap 18-55. Any recommendations on what I should do? Which body would suit my needs with smallest expense? I was just offered a d90 at $680 and wondering if it could be good enough in my situation. I could get a 18-55 VR lens or nikon 20 2.8 prime to go with it. Would it be fast enough to photograph my constantly moving 4-year old? By the way, I haver never printed anything larger than 8x10. So this low noise offered by FF might not be necessary for me. Please share your thought.
