摘要： An imaging lens includes, sequentially from an object side, a first lens (L11) configured by a negative meniscus lens disposed with the convex surface on the object side; a second lens (L12) configured by a positive biconvex lens; a negative third lens (L13); and a fourth lens group (L14) configured by a positive meniscus lens disposed with the convex surface on the image plane IMG side. By satisfying given conditions, the imaging lens is able to control ghosting occurring between the last lens surface and the imaging element and ghosting caused by light reflected by the lens surface nearest the object, without sacrifice to the compact-size of the optical system or high optical performance.

摘要： A zoom lens includes sequentially from an object side, a first lens group having a positive refractive power, a second lens group having a negative refractive power, an aperture stop, and a third lens group having a positive refractive power. The first lens group includes a negative lens and a positive lens. The second lens group includes sequentially from the object side, a negative lens, a negative lens, and a positive lens. The third lens group includes sequentially from the object side a front group having a positive refractive power, a middle group having a negative refractive power, and a rear group having a positive refractive power. The front group is formed by a positive aspheric lens. The middle group is includes a cemented lens formed by a positive lens and a negative lens.
摘要翻译：变焦透镜从物体侧顺序地包括具有正折光力的第一透镜组，具有负折光力的第二透镜组，孔径光阑和具有正折光力的第三透镜组。第一透镜组包括负透镜和正透镜。第二透镜组从物体侧依次包括负透镜，负透镜和正透镜。第三透镜组从物体侧依次包括具有正折光力的前面组，具有负屈光力的中间组和具有正屈光力的后组。前组由正非球面透镜形成。中间组包括由正透镜和负透镜形成的胶合透镜。
