Problems solved by technology
[0002] In the related technology, the mobile phone can adopt a periscope camera, and let the periscope camera lie flat inside the mobile phone. The periscope camera usually has multiple sets of lenses, and the multiple sets of lenses are usually arranged in sequence along the direction of the periscope camera. Arrangement, however, in the direction in which multiple sets of lenses are arranged in sequence, the size of the periscope camera is relatively large, making it difficult to arrange the rest of the components inside the phone

The invention discloses a zoom lens, a camera module and an electronic device. The zoom lens includes a first lens group, a second lens group, a third lens group, and a prism. The first lens group hasnegative focal power. The prism comprises an incident surface, a reflecting surface and an emergent surface which are connected in sequence, and the first lens group is opposite to the incident surface. The second lens group has positive focal power and can move relative to the prism. The third lens group has negative focal power, is opposite to the emergent surface, and can move relative to theprism. According to the zoom lens, the camera module and the electronic device, the first lens group is opposite to the incident surface of the prism, the third lens group is opposite to the emergentsurface of the prism, and the arrangement directions of the first lens group and the third lens group are different, so that the zoom lens is prevented from being relatively large in size in a certaindirection; and arrangement of internal elements of the electronic device is facilitated.
Description
technical field [0001] The present application relates to the technical field of consumer electronics, in particular to a zoom lens, a camera module and an electronic device. Background technique [0002] In the related technology, the mobile phone can adopt a periscope camera, and let the periscope camera lie flat inside the mobile phone. The periscope camera usually has multiple sets of lenses, and the multiple sets of lenses are usually arranged in sequence along the direction of the periscope camera. Arrangement, however, in the direction in which multiple sets of lenses are arranged in sequence, the size of the periscope camera is relatively large, making it difficult to arrange the rest of the components inside the phone. Contents of the invention [0003] Embodiments of the present application provide a zoom lens, a camera module, and an electronic device. [0004] The zoom lens according to the embodiment of the present application includes a first lens group, a s...
