Abstract: A zooming camera module includes a first lens group, a second lens group, and a third lens group. The first lens group is implemented on an optical axis at a fixed position, and has a negative total optical power. The second lens group is implemented on the optical axis and can be moved back and forth along the optical axis, to achieve zooming and focusing. The second lens group has a positive total optical power, and includes a liquid lens unit and at least one lens with non-zero optical power, wherein the at least one lens and the liquid lens are separately or integrally configured. The third lens group is implemented on the optical axis at a fixed position, and has a non-zero total optical power.
