This stands for modulation frequency or spatial frequency, and is measured and graphed using an MTF tester to determine the characteristics of a lens. This is called an MTF chart. In general, the higher the graph, the better the MTF characteristics. Also, it is better to have less variation due to differences in resolution. Lenses were originally displayed using resolution, but nowadays most lenses are displayed using MTF curves. This is largely due to the efforts of Carl Zeiss. Abbreviation for Modular Transfer Function. Source: CameramanWeb Cameraman Photo Terminology Dictionary Information |
変調周波数あるいは空間周波数のことで、レンズの特性をMTF試験器で測定して、グラフ化する。これをMTFチャートという。一般にグラフが上のほうにあるほどMTF特性が良い。また、解像力の違いによる差も少ないほうがいい。レンズはもともと解像力で表示していたが、現在ではMTF曲線がほとんどである。これはカール・ツァイスの努力によるところが大きい。Modular Transfer Functionの略。
