Geometrical MTF Chart
?
10 lines per millimeter measure the lens' contrast ability (red lines), repeating fine parallel lines spaced at 30 lines per millimeter measure the lens' sharpness ability (green lines), when the aperture is wide open.
Diffraction MTF Chart
?
Diffraction MTF takes diffracted light at every aperture into account which is very close to actual image data. Geometrical MTF does not consider the diffraction quality of light, yet it tends to show higher values than actual image.
