What you are seeing is a characteristic of modern focusing screens. Today's screens tend to be optimised for viewfinder brightness and for AF operation. The unfortunate side-effect of this is that the screen is limited in showing the true DoF effect for faster lenses. I think most Nikon screens bottom out DoF-wise at about f/2.8 or so.

I'm afraid I don't understand the technical reason for this, but I'm sure someone will be along soon with a full explanation...
