After a long hiatus from shooting, I am looking for a DSLR to replace my old trusty N70. I have a Nikon 80-200mm f/2.8 AF-D and a Nikon 28-80mm f/3.5-5.6 AF-D. I shoot mostly nature/landscape/wildlife and some portrait/group/events (not sports). I've been looking at the D300s, D700, and D7000 (or possibly wait for the D300s replacement). I'm a bigger guy and have lugged my gear, including tripod, backpacking through the mountains, so weight isn't a huge consideration. I am particularly interested in the trade-offs of a DX body with my FX lenses. Recommendations?
