Abstract: The imaging lens consists of, in order from the object side, a first positive lens group, a stop, a second positive lens group, and a third negative lens group. During focusing, the first lens group and the second lens group move integrally. The first lens group consists of three or less lenses. The first lens group includes a cemented lens in which a negative lens and a positive lens are cemented in order from the object side. The third lens group consists of, in order from the object side, a negative aspheric lens, a negative lens, and a positive lens. The lens closest to the image side in the second lens group is a biconvex lens, and the imaging lens satisfies a predetermined conditional expression regarding the radius of curvature of the surface of the biconvex lens.

Abstract: An imaging lens is constituted by, in order from the object side to the image side, a positive first lens group, a negative second lens group, and a positive third lens group. During focusing operations, the first lens group and the third lens group are fixed, while the second lens group moves. The first lens group has a cemented lens formed by cementing a positive lens and a negative lens together. The second lens group is constituted by two or fewer lenses. The third lens group is constituted by three or more lenses. The surface toward the object side of at least one of the first and second lenses from the object side within the third lens group is concave. A negative lens having a concave surface toward the object side is provided most toward the image side. A predetermined conditional formula is satisfied.
