Abstract
When an optical image is formed through an imaging lens on an imaging surface that is convex toward a light incident side, the imaging lens is constructed in such a manner that a defocus MTF peak position at an arbitrary image height in a range of from 70% to 100% of a maximum image height of the optical image is located further in a light-traveling direction than a same kind of defocus MTF peak position on an optical axis of the imaging lens.

An imaging lens for forming an optical image of an object on an imaging surface that is convex toward a light incident side, wherein a defocus MTF peak position in a sagittal direction or a tangential direction at an arbitrary image height in a range of from 70% to 100% of a maximum image height of the optical image is located further in a light-traveling direction than a same kind of defocus MTF peak position on an optical axis of the imaging lens.
An imaging lens for forming an optical image of an object on an imaging surface that is convex toward a light incident side, wherein defocus MTF peak positions in a sagittal direction or a tangential direction at all of image heights in a range of from 80% to 100% of a maximum image height of the optical image are located further in a light-traveling direction than a same kind of defocus MTF peak position on an optical axis of the imaging lens.
