Abstract

The embodiment of the present application discloses a zoom optical system, a camera module and a terminal device. The zoom optical system includes first and third lens groups with negative refractive power and a second lens group with positive refractive power. The first lens group includes the first and second lenses, the second lens group includes the third, fourth and fifth lenses, and the third lens group includes the sixth lens. The first, fourth and sixth lenses have negative refractive power, the third and fifth lenses have positive refractive power, and the second lens has refractive power. The object side and the image side of the first lens are concave at the near optical axis, the object side of the fourth lens is concave at the near optical axis, and the image side of the sixth lens is concave at the near optical axis. Zoom optical system meets: 1.6

Description

technical field [0001] The present application belongs to the technical field of optical imaging, and in particular relates to a zoom optical system, a camera module and a terminal device. Background technique [0002] It has become a new development trend for terminal equipment to be equipped with an optical system with a zoom function. The zoom optical system can change the shooting range by changing the focal length without changing the shooting distance. Therefore, it is very conducive to the composition of the picture and can meet the various shooting needs of users. [0003] At present, the maximum zoom factor that the zoom optical system can achieve is limited, which limits the zoom range of the zoom optical system, and the total length of the zoom optical system is relatively long. When applied to terminal equipment, due to the limited installation space of the terminal equipment, the zoom optical system will be affected. image quality. [0004] Therefore, how to r...
