Abstract

Provided is an imaging lens, and also provided are an image pickup apparatus and a portable terminal both equipped with the imaging lens. The imaging lens includes in order: a positive first lens having a convex object-side surface; a negative second lens having a concave image-side surface; a negative meniscus-shaped third lens having a convex object-side surface; a positive fourth lens having a convex image-side surface; and a negative fifth lens having a concave image-side surface. The image-side surface of the fifth lens is aspherical and has an inflection point at a position of the optical axis. The third and the fourth lenses are integrally moved to focus, and the following conditional relation is satisfied: 0.75<f34/f<1.30, where f34 is the combined focal length of the third lens and the fourth lens, and f is the focal length of the entire system of the imaging lens.
