Film may have very high absolution resolution (for B/W lines) but the pixel
quality of digial image is just better, see here a scan of RVP50 at 4000dpi
with 4000ED and a 21MP 5D II capture, both taken with 24/2.

A long time back C.H.Ling shared on list some of his comparisons of film
scanner vs microphotographs of the film.
This is is essentially the same, but is done at 2400dpi and 4000dpi, so
gives an idea of what is lost at different scanner resolutions. Remember
that film scanners have nominally a lot better resolution and lower
artifacts than digi cameras, at same dpi, because they don't use Bayer
sensor patterns, so resolution is same for all colors. (Bayer resolution is
half for red and blue versus green).
Contrast and AA filter also affect nominal resolution, so comparisons are
always difficult.
