There is recorded on film DOF...if your lense is sharper than your film can record, you will record at the highest resolution the film is capable of over a certain distance in the image... Then there is printed DOF, that the print can only handle so much resolution, typically less than the film, and any resolution on the film that is more than the printed image can handle will appear at the same sharpness... Then there's human viewable DOF...where the same parts of an image held at 20" will appear out of focus, will appear sharp at 20'...
