DEPTH-OF-FIELD DATA Given distances are calculated for a blur circle diameter of 60 microns and do not include the effect of lens aberrations. For very critical photography and great enlargements this blur will be visible. In such situations the data given for an aperture two f-stops larger should be used (for example, if shooting at f/8, use DOF data for f/4).
