Abstract: An imaging lens consists of a front group, an aperture stop, and a rear group, in order from an object side. The rear group includes at least one Lp lens that is made of a resin, has a positive refractive power, and is cemented to a lens. Assuming that an Abbe number and a refractive index of the Lp lens are respectively νp and Np, the Lp lens satisfies Conditional Expression represented by 120

Abstract: A zoom lens is constituted by, in order from the object side: a positive first lens group; a negative second lens group; a positive third lens group; a negative fourth lens group; and a positive fifth lens group. The distance between the first and second lens groups constantly increases, the distance between the second and third lens groups constantly decreases, the distance between the third and fourth lens groups constantly changes, and the distance between the fourth and fifth lens groups constantly increases when changing magnification from the wide angle end to the telephoto end. The first lens group is constituted by three lenses, which are negative, positive, and positive in order from the object side. The second lens group is constituted by five lenses, which are negative, negative, positive, positive, and negative in order from the object side. The fifth lens group is constituted by a single lens component.

Abstract: A macro lens system includes, in this order from an object side: a positive first lens group; a negative second lens group; a positive third lens group; a positive fourth lens group; a positive fifth lens group; and a negative sixth lens group. The first lens group is constituted by three lenses. The second lens group, the fourth lens group, and the fifth lens group are independently moved in the direction of the optical axes thereof when focusing from an object at infinity to an object at a most proximate distance.

Abstract: An imaging lens consists of, in order from the object side to the image side, a first lens group having a positive refractive power, a second lens group having a negative refractive power, and a third lens group. During focusing, only the second lens group moves. The imaging lens satisfies a conditional expression: −0.5

Abstract: The imaging lens consists of, in order from an object side, a positive first lens group, a positive second lens group, and a negative third lens group. During focusing, only the second lens group moves. The first lens group includes a stop. The second lens group includes one or more cemented lenses in which a negative lens and a positive lens are cemented. The number of the positive lenses included in the second lens group is equal to or greater than three.

Abstract: The imaging lens consists of, in order from the object side, a first lens group having a positive refractive power, a stop, a second lens group having a positive refractive power, and a third lens group. The third lens group includes one or more positive lenses and one or more negative lenses. During focusing, an entirety of the first lens group, the stop, and the second lens group, or an entirety of the second lens group integrally moves as a focus group, and the third lens group remains stationary with respect to an image plane. The imaging lens satisfies predetermined conditional expressions.

Abstract: A zoom lens includes a positive first lens group, a negative second lens group, a positive third lens group, and a positive fourth lens group in order from an object side. In a case of magnification, the first lens group, the second lens group, and the third lens group move. The third lens group consists of a third a lens group that does not move in a case of image shake correction, a third b lens group that moves in the case of the image shake correction, and a third c lens group that does not move in the case of the image shake correction in order from the object side. The third b lens group consists of a positive lens and a negative lens. A predetermined conditional expression related to the third b lens group is satisfied.
