I've been using a D50 for approx 10 years, just as a hobby. Mainly shoot kids sporting events, water sports, family stuff, hiking...Also usually take it on vacations, for instance to PR, Costa Rica, etc. I currently only have 18-55 kit lens, 18-70, 50 1.8, 180 2.8, and 70-200 2.8 VR. The D50 has been great, but it is a little long in the tooth now & I just want something newer. I've been watching d7000 and D7100 prices for a while, and they now seem to be pretty good. Especially the D7000 for 525.00 at Amazon. If I get the D7000, would I miss anything from the D7100? Surely they are both leaps & bounds above my D50. Just looking for some guidance. Been reading this forum for a while, but have never posted until now.
