I think Yardley is referring to the idea that film grain is thicker and more uneven than the photosites on a digital sensor, and that film therefore captures (marginally) more of the "spread" of the focus and so gives the impression of more depth of field.
I don't know if this is true. Sounds somewhat plausible theoretically but like many things, I've read about it on the net and never seen it demonstrated.

I didn't even know that a digital Nikon is a large format camera.
Could it be this is the wrong place/forum for you?
Anyway, though I don't shoot digital, I shoot film, and from time to time with a F4s and a 2.5/105 mm. Stopping down a bit gives plenty DoF for portraits - at (what you call) 'full frame' (which we call it toy format :cool:). A crippled sensor like yours should definitely deliver more DoF. If I were you, I'd send the camera and lens to the next service station, really.

And the size of the circle of confusion that is accepted as being "sharp". This is mainly a matter of definition, but for different formats, different sizes of coc are commonly used.

Try the brenizer method on Portrait and you get the large Format feel you are looking for
