MTF Chart
MTF (Modulation Transfer Function) describes how well a lens can reproduce fine details, measured as the degree of contrast achieved between finely spaced lines.
[1] At 12mm / Max. aperture [2] At 12mm / F8 aperture
[3] At 24mm / Max. aperture [4] At 24mm / F8 aperture
[5] Contrast (%) [6] Distance from optical centre of lens (mm)
[7] Spatial frequency [8] 10 lines pairs / mm [9] 30 line pairs / mm
[10] Radial values [11] Tangential values
