WebIn short, MTF is a measurement of the optical performance of a lens. More specifically, MTF shows the ability of a lens to resolve detail and transmit contrast (light colors remain light and dark colors remain dark). MTF is the acronym for "Modulation Transfer Function". Modulation refers to change. Webhigher mathematics of Fourier-optics. After reading the paper you will be able to conclude about the character of a lens from MTF data published by makers or testing institutes. …
