I agree. Even now I clean my D7000 more than my D600. Still not a big deal. The amount of dust you see is also dependent on what you do with image. If it's a small aperture and you push your processing with HDR or even soft contrast in Silver Efex and look at a clear sky, you will see every speck on every camera.
