Abstract

An imaging optical lens system includes, in order from an object side to an image side along a travelling direction of an optical path, a movable lens group (Gm), a last lens group (Gn) and a prism (E6, LF). The imaging optical lens system undergoes a focus adjustment process to transition from a first state to a second state when an imaged object moves from an infinite object distance to a finite object distance. The movable lens group (Gm) is moved along an optical axis relative to the last lens group (Gn) during the focus adjustment process. An object-side surface of one lens element nearest to the object side within the imaging optical lens system is convex in a paraxial region thereof. No lens element is located between the last lens group (Gn) and the prism (E6, LF). The prism (E6, LF) has at least three reflective surfaces (RF1, RF2, RF3).
