My camera is a Nikon D7000, they now have the D7100, It has a few upgrades like better low light autofocus more megapixels, not much more than what was in the D7000 but enough that I would have purchased it instead. My mostly used lens is a Sigma 120-300mm f2.8 sport. Do not worry about upgrading your camera very often but buy the very best lenses you can afford. Lenses you will own for years and years, camera bodies are always getting better and cheaper. (exept the pro bodies a Nikon D4 is around 6000).
