Abstract:
An imaging lens substantially consists of six lenses of a negative first lens, a negative second lens, a positive third lens, a positive fourth lens, a negative fifth lens and a positive sixth lens in this order from an object side. When a curvature radius of an object-side surface of the fourth lens is R8, and a curvature radius of an image-side surface of the fourth lens is R9, and an Abbe number of the material of the third lens for d-line is νd3, and an Abbe number of the material of the fifth lens for d-line is νd5, the following conditional formulas (1) and (6) are satisfied: −0.61
