Depends on the focal length of the lens and aperture and film format.
But yes even with relatively slow lenses you can have very shallow DOF
even on large format.
A not uncommon lens for portraits with medium format would be something
like 210mm with a maximum aperture of f6.7. At a distance of 7 feet,
DOF would be about between 4 and 5 inches, wide open. The equivalent of
that on 35mm would be a 55mm which at 7 feet would have a DOF of between
4 and 5 inches at f1.4.

You'll never get the imaging characteristics of a banquet camera by
stuffing more bazillion pixels into a 35mm format sensor.
Does the speed graphic really have that shallow of a depth of field
wide open? Or does it also have some tilt capacity which narrows the
depth of field even more?
