Let me try again. I have a D70, a D200, and a D800. I don't have a D300, but I do have a D200 and its viewfinder has the same magnification as the D300.
Viewfinder magnification specs: D70 viewfinder is 0.75X. D200 viewfinder is 0.94X. D300 viewfinder is 0.94X. D800 viewfinder is 0.70X.
This means that the physical size of the subject in the viewfinder on the D70 will be smaller than the D200 and D300 but it will be almost the same as the size of the subject in the D800.
When you attach a DX lens to the D800, it places a box in the viewfinder of the D800. When you take a picture, you will capture only what is inside that box.
I brought the viewfinder to my eye to visually compare DX lenses on each of my cameras.
The items in the D200 viewfinder are the largest when the lenses are all set to the same focal length. When I set the focal length to 55 mm on the D200, I see exactly the same size subject as on the D800 set to 82.5mm.
The subject in the D70 viewfinder is almost exactly the same size as the D800 when the lenses are set to the same focal length.
The DX BOX in the D800 viewfinder is almost the same size as the full D70 viewfinder size. The subject looks the same size.
