>>3795987That is a lot to accomplish well with $2k, but then again I don't believe in buying kit-quality lenses.
D700 ~$250 (cheaped out here for good lenses)
Nikon 24-70 f2.8 ~$600 (you don't need VR for landscapes, great for general shooting)
Nikon 70-200 f2.8 VR ~$800 (sports, you need the speed)
TC-20E 2x TC ~$180 (use with the 70-200, decent for wildlife)
Nikon 105 f2.8D ~$220 (best macro lens on a budget, hands down)
Total: $2,050
You now have 3 high quality workhorse lenses that will last forever and a good body. I would suggest Canon equivalents but I just recently bought a Canon 6D and don't have a good feel for the used market's prices yet. The above is similar to my setup but instead of using a TC with my 70-200mm for wildlife I have a 200-500mm f5.6 VR. If you don't want a bulky 24-70 f2.8 for general shooting and landscapes a 24-85 VR is a good lens for the price (~$200 used) and then you can use the savings on a newer body. Spend $300 more on a body and get a D610 which is faster and has better low light performance for your sports and wildlife (this is what I have, my D700 is a backup). The D700 is a great camera, but the D610 is better all around. Less noise, better dynamic range, faster all around, and the extra resolution doesn't helps when you're doing macro and wildlife and want to crop tight.
