Problems solved by technology

The existing zoom lens group cannot calibrate each lens when adjusting the position of each lens, and there is a certain radial offset between each lens
The zoom lens group is a precision part, even if the offset is small, it will still seriously affect the shooting effect, and the user experience is not good

Abstract

The invention discloses a zoom lens group. The zoom lens group comprises a protective cover, a first magnetic attraction device and at least two lenses, the protective cover comprises an installationcavity, and the first magnetic attraction device is connected to the protective cover. Each lens is movably arranged in the mounting cavity, each lens is provided with a second magnetic attraction device, and the first magnetic attraction device can attract the second magnetic attraction device to calibrate each lens, so that the axial leads of each lens coincide with each other. According to thezoom lens group, the first magnetic attraction device and the second magnetic attraction device are installed on the protective cover and the lens respectively, the first magnetic attraction device attracts the second magnetic attraction device to calibrate the positions of each len, the axes of the lenses coincide, the precision of the zoom lens group is improved, the shooting effect can be improved, and the user experience is good.

Description

technical field [0001] The present application relates to the technical field of optical products, in particular to a zoom lens group. Background technique [0002] The zoom lens group is a camera lens that can change the focal length within a certain range to obtain different wide and narrow field of view angles. The zoom lens group can change the shooting range by changing the focal length without changing the shooting distance. Since one zoom lens group can be used as several fixed-focus lenses, it not only reduces the number of photographic equipment to be carried when traveling, but also saves the time for changing lenses. [0003] Multiple lenses are arranged in the zoom lens group, and the focal length of the zoom lens group can be adjusted by adjusting the distance of each lens. The existing zoom lens group cannot calibrate each lens when adjusting the position of each lens, and there is a certain radial offset between each lens. The zoom lens group is a precision...
