Abstract: A variable-magnification optical system (ZL) comprises: a first lens group (G1) having a positive refractive power; and a rear group (GR) including a plurality of lens groups. When changing the magnification, the gap between each adjacent pair of lens groups changes. The plurality of lens groups in the rear group (GR) include a second lens group (G2) having a positive refractive power and disposed nearest to the object side in the rear group (GR). The variable-magnification optical system (ZL) satisfies the following conditional expression: 0.15

Abstract: A zoom optical system includes a positive first lens group, a negative second lens group disposed on an image side of the first lens group, a positive third lens group disposed on an image side of the second lens group, a negative fourth lens group disposed on an image side of the third lens group, and a final lens group disposed on an image side of the fourth lens group and closest to an image. During zooming, distances between lens groups change, and the first lens group moves along an optical axis. A negative focusing lens group is provided, and the final lens group is disposed on an image side of the focusing lens group. A negative vibration proof group of the second lens group may include, in order from an object, a negative lens, an air gap and a cemented lens of a negative lens and a positive lens. The final lens group may have negative refractive power.

Abstract: An optical imaging lens includes first to third lens element groups in sequence along an optical axis from an object side to an image side. The first lens element group includes at least two lens elements. The second lens element group includes at least two lens elements. The third lens element group includes at least two lens elements. When the optical imaging lens is zoomed, at least one lens element group is moved toward a direction of the object side or the image side along the optical axis.
