摘要： An image lens assembly includes, in order from an object side to an image side along an optical path, a first lens group, a second lens group, a third lens group and a fourth lens group. A total number of lens elements in the image lens assembly is seven. The first lens group includes a first lens element with positive refractive power and a second lens element with negative refractive power. Each of the second lens group and the third lens group includes at least one lens element. The fourth lens group includes a seventh lens element. When the image lens assembly is focusing or zooming, a relative position between the first lens group and an image surface is fixed, a relative position between the fourth lens group and the image surface is fixed, and the second lens group and the third lens group move along the optical axis.

摘要： An image lens assembly includes four lens groups: a first lens group, a second lens group, a third lens group and a fourth lens group along an optical path. The four lens groups include nine lens elements: a first lens element with positive refractive power, a second lens element with negative refractive power, a third lens element, a fourth lens element, a fifth lens element, a sixth lens element, a seventh lens element, an eighth lens element and a ninth lens element along the optical path. At least one lens element of the image lens assembly has at least one inflection point. At least five lens elements of the image lens assembly are made of plastic material. When focusing or zooming, the first lens group and the fourth lens group stay stationary, while the second lens group and the third lens group move along an optical axis.
