MTF graphs
The MTF is indicated both at full aperture and at
f/5.6 at long taking distances (infinity). Shown
is the contrast in percentage for 5, 10, 20 and
40 lp/mm accross the height of the 35 mm film
format, for tangential (dotted line) and sagittal
(solid line) structures, in white light. The 5 and
10 lp/mm will give an indication regarding the
contrast ratio for large object structures.The
20 and 40 lp/mm records the resolution of finer
and finest object structures.
