Abstract: The imaging lens consists of, in order from an object side, a first lens group, a stop, a positive second lens group, and a negative third lens group. The second lens group includes a negative lens and a positive lens. During focusing, the second lens group moves, and the third lens group does not move. Image blur correction is performed by moving the entire third lens group or a part of the third lens group in the direction intersecting the optical axis.

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.

Abstract: The imaging lens substantially consists of a first lens group having positive refractive power, an aperture stop, and a second lens group having positive refractive power, in this order from the object side. The first lens group consists of, in this order from the object side, an eleventh lens group and a twelfth lens group with a largest air space therebetween. The eleventh lens group has at least one negative lens with a concave surface toward the image side, having negative refractive power; and the twelfth lens group has positive refractive power. The second lens group substantially consists of, in this order from the object side, an aspheric lens having at least one aspheric surface, a positive lens, a negative lens, and a three-cemented lens formed by cementing a positive lens, a negative lens, and a positive lens in this order from the object side.

Abstract: The imaging lens consists of, in order from the object side, a first lens group having a positive power, a second lens group having a negative power, and a third lens group. The first lens group consists of, in order from the object side, a positive front group, a stop, and a positive rear group. The rear group has a cemented lens consisting of a negative lens concave toward the image side and a positive lens convex toward the image side in order from the object side. The second lens group consists of a negative lens. During focusing, only the second lens group moves. The following conditional expression relating to a focal length f2 of the second lens group and focal length f of the whole system is satisfied: 0.8

Abstract: An imaging lens includes, consecutively in order from the most object-side, a positive first lens group, a positive second lens group and a third lens group. Focusing on an object at close distance from a state of having focused on an object at infinity is performed by moving the second lens group and the third lens group in such a manner that a distance between the second lens group and the third lens group changes while the first lens group is fixed. The first lens group includes, consecutively in order from the most object-side, a negative first lens and a negative second lens.

Abstract: An imaging lens consists of a front group having positive refractive power as a whole and a rear group in this order from an object side. The front group consists of three positive lenses, a negative lens with its concave surface facing an image side, a positive lens with its convex surface facing the object side, a negative lens with its concave surface facing the image side, a stop, a negative lens with its concave surface facing the object side and plural positive lenses in this order from the object side. The rear group has positive refractive power and consists of a positive lens and a negative lens in this order from the object side.
