Problems solved by technology

[0004] At present, for high-magnification camera devices, the volume is usually large. At the same time, due to the addition of anti-shake technology, both the axis radius of the camera device and the total length of the camera device are relatively large, resulting in a further increase in the size of the camera device. The camera device is inconvenient to use, which also reduces the scope of application of the camera device

Abstract

The invention relates to the technical field of camera shooting, in particular to a camera shooting device and a zoom lens. Comprises: a zoom lens; and an image pickup element configured to receive an image formed by the zoom lens; the zoom lens is composed of six lens groups. The zoom lens sequentially comprises a fixed lens group with positive focal power, a first zoom lens group with negative focal power, a second zoom lens group with positive focal power, a diaphragm, a third zoom lens group with negative focal power, an anti-shake lens group with negative focal power and a focusing lens group with positive focal power from an object plane side to an image plane side, according to the technical scheme, the small-size and large-magnification camera device is realized, meanwhile, the anti-shake lens group can be arranged at the position of the rear group through the arrangement of the anti-shake lens group, the longitudinal anti-shake effect can be realized while focusing is realized, and the application range of the camera device is enlarged.

Description

technical field [0001] The invention relates to the technical field of imaging, in particular to an imaging device and a zoom lens. Background technique [0002] There are many types of camera devices, and the basic principle of their work is the same: to convert optical image signals into electrical signals for storage or transmission. When we shoot an object, the light reflected on the object is collected by the lens of the camera device, making it focus on the light-receiving surface of the camera device, and then the light is converted into electrical energy by the camera device, and a "video signal" is obtained. [0003] With the continuous development and progress of the technological level, users have higher and higher requirements on the imaging quality of the camera device, and it has become an inevitable trend to apply anti-shake technology to the camera device. Anti-shake technology can be divided into three types: optical anti-shake, electronic anti-shake and ph...
