摘要： The present disclosure discloses a zoom lens assembly. The zoom lens assembly comprises, sequentially along an optical axis from an object side to an image side, a first lens group comprising a first lens and a second lens; a second lens group having a positive refractive power and comprising a third lens, a fourth lens and a fifth lens; a third lens group having a negative refractive power and comprising a sixth lens; and a fourth lens group having a positive refractive power and comprising a seventh lens and an eighth lens. At least one of the first lens to the eighth lens is an aspheric lens. By changing positions of at least two lens groups in the second lens group, the third lens group and the fourth lens group on the optical axis, the zoom lens assembly switches between a wide-angle state and a telephoto state, and a focal length of the zoom lens assembly changes linearly when the zoom lens assembly switches from the wide-angle state to the telephoto state.
