The implementations described in the following exemplary examples do not represent all implementations consistent with the utility model. Rather, they are merely examples of apparatus and methods consistent with aspects of the utility model as detailed in the accompanying claims.

In the description of the present utility model, it should be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "height", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential", etc. indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings, are merely for convenience in describing the present utility model and simplify the description, and do not indicate or imply that the device or element being referred to must have a specific orientation, be configured and operated in a specific orientation, and therefore should not be construed as limiting the present utility model.

Unless defined otherwise, all technical terms used in the embodiments of the present utility model have the same meaning as commonly understood by one of ordinary skill in the art.

The iris diaphragm can be used for adjusting the light entering quantity of a camera lens, and can enable a user to take better pictures under different illumination conditions. The principle of the iris diaphragm is to change the diaphragm size of the lens by a set of rotatable or movable blades. The user can switch the aperture size according to different shooting scenes to obtain the optimal light entering quantity and ensure a better imaging effect. Because the aperture has great influence on the improvement of imaging quality, the heat of the aperture is higher and higher in recent years, and the iris aperture gradually becomes the standard configuration of flagship models of various large manufacturers.

The most significant visual impact that a variable aperture can produce is the change in depth of field: the larger the aperture is, the smaller (shallow) the depth of field range is, the more obvious the blurring effect of the background is, the more prominent the shooting subject can be, and the imaging subject is suitable for taking close-ups; the smaller the aperture, the larger (deep) the depth of field range, the sharper the background, and all elements in the scene are clear, thus being suitable for scenery shooting. Under the condition that the shutter speed and the light sensitivity are unchanged, the larger the aperture is, the more the lens light enters, the more the light captured by the camera is, and the higher the brightness of the shot picture is. Depending on the purpose and scene of the shot, an appropriate aperture size may be selected. Generally speaking: when shooting subjects with the main body and background blurring needing to be highlighted, such as portrait close-up, flower and grass details and the like, a large aperture can be selected; when shooting subjects such as scenery, buildings, static objects and the like which need to keep panorama clear and large depth of field, a small aperture can be selected; when shooting the subjects needing to generate starburst effect such as night lights, starry sky and the like, a small aperture can be selected.

In the related art, the iris diaphragm includes a rotating member and a plurality of blades (typically six or more blades), and the rotating member drives the plurality of blades to rotate, so that the size of an aperture hole formed by surrounding the plurality of blades is changed. However, the number of blades of the prior iris diaphragm is large, a motion mechanism is complex, and action clamping stagnation is easy to generate in the rotation process, so that the use experience of a user is influenced.

Therefore, the embodiment of the utility model provides the iris diaphragm which has the advantages of less blades, simple structure and difficult generation of action clamping stagnation in the moving process of the blades, so as to ensure that a user can have good use experience.
