Abstract
An imaging lens has a negative first-lens, a first-cemented-lens of a second-lens and a third-lens, a stop, a positive fourth-lens, and a second-cemented-lens of a fifth-lens and a sixth-lens in this order from an object-side. The first-lens has a plano-concave or meniscus shape with a concave image-side surface. One of the second-lens and the third-lens is a positive lens and the other one is a negative lens. An object-side surface of the fourth-lens is a flat surface or a surface with a curvature radius having an absolute value greater than that of its image-side surface. One of the fifth-lens and the sixth-lens is a positive lens and the other one is a negative lens.
