Preferably, the sensing member 22 is a correlation type photoelectric switch.

Specifically, the zoom lens main body 1 is a manual zoom lens in the prior art, and a user changes the position of a lens module in the zoom lens main body 1 by controlling the rotation of the rotating member 24, so as to change the magnification of the zoom lens main body 1; when the rotating part 24 rotates, the signal triggering part 23 is driven to rotate, so that the check ring 25 on the signal triggering part 23 can trigger or block the signal of the sensing part 22, the signals of the sensing parts 22 trigger, and the signals of the sensing parts block some signals, so that different signal permutation and combination can be formed, each signal permutation group represents a multiplying power, when the multiplying power of the zoom lens main body 1 is changed, the signal permutation condition of the sensing parts 22 can be triggered and determined, and the multiplying power of the zoom lens main body 1 can be determined quickly and conveniently. The control panel 21 is connected with a control terminal such as a computer, and the signal of the sensing element 22 is transmitted to the computer through the control panel 21, so that the magnification at the corresponding position can be obtained on the computer according to the signal arrangement of the photoelectric signal switch, and in practical application, a user only needs to rotate and adjust the rotation angle of the rotating element 24, and the corresponding lens magnification can be obtained.
