Abstract:
The present disclosure relates to a zoom imaging lens, an imaging apparatus, and an electronic device. The zoom imaging lens comprises a first lens group and at least one liquid lens assembly; the first lens group and the at least one liquid lens assembly are sequentially arranged from an object side to an image side along the optical axis of the zoom imaging lens; the first lens group is fixed along the position of the optical axis; the liquid lens assembly comprises a fluid and a thin film; the fluid is wrapped by the thin film; the thin film can be deformed and light-transmitting; the shape of the thin film can change with an external force; the focal length of the liquid lens assembly changes when the shape of the thin film changes; and the focal length of at least one of all the liquid lens assemblies changes, so as to achieve zooming or focusing of the zoom imaging lens. The technical solution of the present disclosure can reduce the total length, volume and assembly tolerance of the zoom imaging lens, thereby reducing the manufacturing difficulty.
