MTF graphs
The MTF is indicated at full aperture and at
f/5.6 and f/8.0 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.
