WebA high-end lens with an MTF-50 of 50 LP/mm will appear far sharper than a lower quality lens with an MTF-50 of 20 LP/mm, for example (presuming that these are used on the same camera and at the same aperture; more on this later). However, the above MTF versus frequency chart is not normally how lenses are compared. Web6 dec. 2024 · Modulation Transfer Function (MTF) is an important method of describing the performance of an optical system.
