Abstract: A first lens group having positive refractive power and a second lens group are arranged in this order from an object side, and only the first lens group moves in the optical axis direction while focusing. The first lens group substantially consists of a positive 1-1 lens, a positive 1-2 lens, a positive 1-3 lens, a negative 1-4 lens, an aperture stop, a negative 1-5 lens, a positive 1-6 lens, and a positive 1-7 lens. The 1-3 lens and the 1-4 lens are cemented to each other, and the 1-5 lens and the 1-6 lens are cemented to each other. The second lens group substantially consists of a negative 2-1 lens and a positive 2-2 lens. Only the first lens group moves in the optical axis direction while focusing.
Abstract translation: 具有正屈光力的第一透镜组和第二透镜组从物体侧依次布置，并且仅第一透镜组在聚焦的同时沿光轴方向移动。 第一透镜组基本上由正1-1透镜，正1-2透镜，正1-3透镜，负1-4透镜，孔径光阑，负1-5透镜，正1-透镜组成， 6透镜和正1-7透镜。 1-3透镜和1-4透镜彼此粘合，1-5透镜和1-6透镜彼此粘合。 第二透镜组基本上由负2-1透镜和正2-2透镜组成。 聚焦时，只有第一个镜头组在光轴方向移动。

Abstract: The imaging lens includes, as lens groups, only a positive first lens group, a positive second lens group, and a negative third lens group in order from the object side. An aperture stop is disposed between a lens surface closest to the image side in the first lens group and a lens surface closest to the object side in the third lens group. During focusing, the first lens group and the third lens group do not move, and the second lens group moves. The first lens group consists of a negative lens and a positive lens in order from the object side. The third lens group has a negative lens and a positive lens in order from the object side.

Abstract: A rear converter lens consists of, in order from the object side, a positive first lens group, a negative second lens group, and a positive third lens group. The first lens group consists of a cemented lens in which a negative lens concave toward the image side and a positive lens convex toward the object side are cemented, the second lens group consists of a cemented lens in which a negative lens concave toward the image side, a positive lens convex toward both sides, and a negative lens concave toward the object side are cemented, and the third lens group consists of, in order from the object side, a third lens group-first lens that is a positive lens convex toward the object side and a third lens group-second lens that is a negative lens.

Abstract: A five-group zoom lens including, in order from the object side, positive, negative, negative, positive, and positive groups. The first group includes a negative meniscus lens with the concave surface toward the image side, a positive lens and a positive lens. The second group includes a negative lens with the image-side surface having an absolute value of curvature radius smaller than that of the object side surface, a biconcave lens, and a biconvex lens. The third group includes a negative lens with the object side surface having an absolute value of curvature radius smaller than that of the image-side surface, and is moved during focusing on a closer object. The fifth group includes a positive fifth-A group including a biconvex lens, and a negative fifth-B group including a biconcave lens and a biconvex lens, wherein condition expression (1) is satisfied: 0.22
