| Abstract | Provided is a low-cost and compact super-wide-angle anamorphic lens having small number of lenses and exhibiting excellent lens performance when the lens is used for an onboard camera, capturing of an unwanted portion is minimized. The super-wide-angle anamorphic lens has an angle of view of 180°or more in the horizontal direction, and includes a first lens having a negative power, a second lens having a negative power, a third lens having a positive power, a fourth lens having a positive power in that order from, an object side. One of the aforementioned third lens and fourth lens is provided with at least one non-rotationally symmetric aspherical surface. |
