摘要: Disclosed is an image capturing lens system. The image capturing lens system includes an image capturing lens group having a plurality of lenses and a phase mask located in the image capturing lens group. The phase mask may satisfy phase mask functions that are defined with respect to x and y axes such that a modulation transfer function (MTF) of light is uniformized.
