The MTF is indicated both at full aperture and
atf/5.6 at long taking distances (infinity). Shownis
the contrast in percentage for 5, 10, 20 and40
lp/mm accross the height of the 35 mm filmformat,
for tangential (dotted line) and sagittal(solid line)
structures, in white light. The 5 and10 lp/mm will
give an indication regarding thecontrast ratio for
large object structures.The20 and 40 lp/mm
