先把F数们都搬出来:

Conventions and Definitions > Working F/#

Conventions and Definitions > Paraxial Working F/#

Conventions and Definitions > Image Space F/#

总结一下,

Working F/#最准,因为它基于实际光线计算。

Paraxial Working F/#也考虑物像位置关系,不过用的是近轴边缘光线的计算。

Image Space F/#是大家比较熟悉的F数的定义,也就是焦距/入瞳尺寸。


还有个

 Effective F/#,这里也提一下。

The Analyze Tab (sequential ui mode) > Image Quality Group > Extended Scene Analysis > Relative Illumination
