摘要： An imaging optical system consists of: a first lens group having positive power; a second lens group having negative power; and a third lens group having positive power. The second lens group moves along an optical axis of the optical system toward an image plane, while the optical system is focusing to switch from an infinity in-focus state to a close-object in-focus state. The first lens group includes a negative lens having a convex surface facing the object and located closest to the object. The second lens group is located closer to the image plane than an aperture stop and consists of: a positive lens having a convex surface facing the object; and a negative lens. The third lens group consists of three or more lenses including one or more negative lenses. One of the three or more lenses which is located closest to the object is a positive lens.

摘要： An optical photographing system includes seven lens elements which are, in order from an object side to an image side along an optical path: a first lens element, a second lens element, a third lens element, a fourth lens element, a fifth lens element, a sixth lens element and a seventh lens element. Each of the seven lens elements has an object-side surface facing toward the object side and an image-side surface facing toward the image side. The object-side surface of the sixth lens element is convex in a paraxial region thereof. At least one of the object-side surface and the image-side surface of at least one lens element of the optical photographing system has at least one inflection point.
