    How many times have you looked at a print and it is not as detailed as
you recall seeing it in the view finder. The eyes ability to distinguish
detail is remarkable - only the field of vision is very narrow. I am anxious
to know my self.
    The exception of the above is with low speed B&W film. For what is
worth, the resulting resolution of the film and optical system is:

1/R = 1/O X 1/F

where     R = resolution of the negative
              O = resolution of the optical system
              F = resolution of film
Colour negative film rates anywhere from 80 to 125 lpm and B&W 150 and
upwards
