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.
For these situations we recommend a conservative use of the DOF data. In such situations the data given for an aper-
ture two f-stops larger should be used (for example, if shooting at f/8, use DOF data for f/4).
To convert meters into feet, multiply by 3.281. To convert meters into inches, multiply by 39.37
