摘要： 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

摘要： A single-focal-length imaging lens system achieves focusing by, while keeping first and third lens groups stationary relative to the image plane, moving a second lens group along the optical axis. The second lens group includes a positive lens element. The third lens group includes an aspherically shaped lens element having an inflection point at a position other than the intersection with the optical axis. The first and second air lenses formed by the intervals between the first and second and between the second and third lens groups have negative and positive refractive powers respectively. The conditional formula 0≦|Fi1/Fi2|−|Fm1/Fm2|≦10 is fulfilled (Fi1 and Fi2 representing the focal lengths of the first and second air lenses, respectively, when focusing on the infinite object distance; Fm1 and Fm2 representing the focal lengths of the first and second air lenses, respectively, when focusing on the closest object distance).
