The D600 has the same dust and oil issues, as the D7000 had.I bought a D7000, when it came out.I had it clean twice in less than one year. After the second clean up, about a 100 shots after, the oil started again. The camera had about 5000 shots.I sold it on EBay and bough a D300s. Very happy with my choice.5000 shots so far, no oil no dust. Never will buy a Nikon, not beforeAfter one year of production.
