Problems solved by technology

[0003] 1. Complex structure
The existing zoom lens uses a motor to drive several lenses to achieve the zoom function. The structure is complex, the weight is heavy and the volume is large. If the power is insufficient to drive the motor, the camera cannot be used at all.
[0004] 2. Complex focusing
Existing zoom lenses use a motor to adjust the distance of different lenses to achieve the function of focusing. Sometimes a single lens is adjusted, and sometimes more than two lenses need to be adjusted. The process is quite complicated.
[0005] 3. High-magnification lenses are expensive
Depending on actual usage requirements, when long-distance shooting is required, lenses with extremely high multiples may be required, and the cost is quite high

Abstract

Disclosed is a soft zoom lens which comprises a clipper, a mount bracket, a first lens and a second lens. Wherein the clipper includes an inner space, a first end and a second end which are connected to each other via the inner space, the clipper is adjustable along the axle; the mount bracket is soft material and installed in the space of the clipper; the first lens is soft material and has a first plane and a second plane, the first lens is installed in the space of the clipper and located between the first end and the mount bracket; the second lens is soft material which has a first plane and a second plane, the second lens is installed in the space of the clipper and located between the second end and the mount bracket; the curvatures of the first and second lens can be changed by adjusting the clipper to realize variable-focus.

Description

technical field [0001] The invention relates to a soft zoom lens. Background technique [0002] Existing cameras or video cameras are used to accurately capture far or near objects, so the lens must have a zoom function, and the existing zoom lens has the following disadvantages: [0003] 1. Complex structure. The existing zoom lens uses a motor to drive several lenses to achieve the zoom function. The structure is complex, the weight is heavy and the volume is large. If the power is insufficient to drive the motor, the camera cannot be used at all. [0004] 2. Focusing is complicated. Existing zoom lenses use a motor to adjust the distance of different lenses to achieve the function of focusing. Sometimes a single lens is adjusted, and sometimes more than two lenses are adjusted. The process is quite complicated. [0005] 3. The cost of high-magnification lenses is high. Depending on the actual use requirements, when long-distance shooting is required, lenses with extre...
