MTF GRAPHS
The MTF is indicated both at full aperture and at f/5.6 for long distances
(infinity) and close focussing distance. Shown is the contrast in percentage
for 5, 10, 20 and 40 lp/mm across 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.
