<P>PROBLEM TO BE SOLVED: To suppress quality deterioration in an imaging lens when forming an optical image on an imaging surface convex on a light incidence side. <P>SOLUTION: An imaging lens 100A is constructed in a manner that when an optical image 1K is formed through the imaging lens 100A on an imaging surface 210 convex on a light incidence side, a defocus MTF peak position Pa1 at any height in a range of from 70% to 100% of a maximum image height Hmax of the optical image 1K is located further in a light-traveling direction than a same kind of defocus MTF peak position Pao on an optical axis Z1. <P>COPYRIGHT: (C)2012,JPO&INPIT |
