发明名称 撮影レンズ、この撮影レンズを備えた光学機器、撮影レンズの製造方法
摘要 An imaging lens, an optical apparatus equipped therewith, and a method for manufacturing the imaging lens are disclosed. An imaging lens consists of, in order from an object, a front group having negative power, and a rear group including a sub-lens group having negative power. At least a portion of the sub-lens group is movable in a direction including a component substantially perpendicular to an optical axis. The sub-lens group includes, in order from the object, a first negative component having negative power, a second negative component having negative power and a positive component having positive power. The shape of an air lens formed by the first negative component and the second negative component is a double convex shape. An antireflection coating is applied on at least one optical surface of the front group, and the antireflection coating including at least one layer formed by use of a wet process.
