In this review, I would like to point potential buyers to something else:
Apparently so have some cameras soiled sensors factory! Part with dust, some of them even with oil stains, which are believed to be caused by the locking mechanism.
Unfortunately my D600 was affected. The patches I got unfortunately even after several cleaning cycles with the bellows are not removed, so I had to return the camera.
Because of this lack of quality assurance I forgive only three stars (though the camera is great in itself)
Potential buyers I would recommend:
On receipt make test shots record with a small aperture a white surface and examine the image on dust spots. If there are too many and / or too stubborn, rather then return the camera. Unless you really know each other well with sensor-wet-cleaning of. I - and certainly many others - trust me to not.

The withdrawal by Amazon worked usual problems.
My conclusion after several tests with the new body: No oil stains / dust out of the box and to the extent no problems after about 350 shots ("normal" images and the described "white wall").
Dust generated by objective change is normal, and easy to remove.
So I raise my rating from 3 to 4; a point deduction but still improvable because of quality assurance at Nikon.
But in order to formulate clear again: fun camera definitely! :-)
