Embodiment Construction
[0056] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.
[0057] It should be noted that if there is a directional indication (such as up, down, left, right, front, back...) in the embodiment of the present invention, the directional indication is only used to explain the position in a certain posture (as shown in the accompanying drawing). If the specific posture changes, the directional indication will also change accordingly.
[0058] In addition, if there are descriptions involving "first", "second" and ...

The invention discloses a telescopic three-group continuous zoom lens and a mobile phone. The telescopic three-group continuous zoom lens comprises a lens main body, and the direction from the object space to the image space along the optical axis of the lens main body is from front to back; the lens main body comprises a lens barrel, a zoom lens group, a compensation lens group and a driving device, the lens barrel is arranged in the front-back direction, and a cavity is formed in the lens barrel; the zoom lens group is movably arranged in the cavity in the front-back direction, and comprises a first lens group and a second lens group which are arranged at an interval from front to back; the compensation lens group is movably arranged in the cavity in the front-back direction and comprises a third lens group with negative focal power, and the third lens group is arranged on the rear side of the second lens group and is spaced from the second lens group; and the driving device is in driving connection with the zoom lens group and the compensation lens group. According to the scheme, the lens main body can be conveniently applied to the electronic equipment which has an imaging function and is relatively thin in thickness.
Description
technical field [0001] The invention relates to the technical field of optical lenses, in particular to a telescopic three-group continuous zoom lens and a mobile phone. Background technique [0002] In recent years, consumers have continuously increased their requirements for the performance and experience of mobile phone photography, and the zoom capability of mobile phone lenses has also attracted more and more attention. At present, mobile phone lenses basically use fixed-focus lenses with different focal lengths. The focal length change between fixed-focus lenses is realized by digital zoom. There is no real optical continuous zoom lens, and digital zoom is realized by cutting and zooming the picture. , which affects the image quality. The optical continuous zoom lens can achieve continuous zooming within a certain focal length range by moving some lenses and changing the distance between the lenses. This kind of lens has good imaging quality at different focal lengths...
