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