Abstract
The utility model relates to a lens for photograph, particularly a multistage focal length adjusting and changing lens. The multistage focal length adjusting and changing lens comprises lens bodies, a camera plug 20, diaphragm bodies 18, light changing rings 19, lenses 21, wherein, the diaphragm bodies 18, the light changing rings 19 and the lenses 21 are arranged on the lens bodies. The utility model is characterized in that the multistage lens bodies are connected with each other through multiple threads. Because the utility model use the multiple thread connectors to connect a set of or a plurality of sets of lens bodies, the focal length can be arbitrarily and quickly adjusted and changed. The multistage focal length adjusting and changing lens can be suitable for various photograph environments.
Description
The utility model relates to a kind of photography camera lens, the multistage focusing zoom lens of particularly a kind of energy.
Existing zoom shot camera lens generally by a lens body and camera plug and the aperture body arranged on lens body, become the ring of light, eyeglass etc. constitutes, its weak point is: have only the one-level focusing, its focusing, zooming range are narrow and little, influence its usable range.
The purpose of this utility model designs a kind of simple in structure exactly, the camera lens of the multistage focusing zoom of energy.
The purpose of this utility model is the multistage focusing zoom lens of realizing by following structure, include lens body and camera plug and the aperture body on lens body, become the ring of light and eyeglass, it is characterized in that: lens body is multistage lens body, is connected by the multi-step thread connector between lens body and the lens body; Can processing such as multi-step thread connector at different levels is focused, zoom during use by regulating.
That the utility model compared with prior art has is simple in structure, can multistagely be used in combination, zoom, focusing arbitrarily, can determine advantages such as zoom ratio rapidly, suitable various special effect cinematography needs.
Description of drawings of the present utility model is as follows:
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is another embodiment of the present utility model;
Among the figure: 1, draw ring, 2, the zoom ring, 3, slide rail, 4, base body, 5, draw ring, 6, zoom ring, 7, connected body, 8, slide rail, 9, the zoom ring, 10, mirror holder, 11, zoom body, 12, the zoom ring, 13, the zoom ring, 14, the zoom body, 15, the zoom ring, 16, connected body, 17, the spacer ring, 13, the aperture body, 19, become the ring of light, 20, plug, 21, eyeglass, 22, slip ring, 23, the zoom body, 24, zoom ring, 25, base body, 26, screw, 27, chute.
The utility model is described in further detail below in conjunction with drawings and Examples:
As shown in Figure 1: the utility model includes lens body and camera plug 20 and the aperture body 18 on lens body, become the ring of light 19, eyeglass 21, its principal character is: lens body be multistage lens body, lens body with lens body between be connected by the multi-step thread connector; Also can intrinsic eyeglass in the multi-step thread connector, to increase focusing progression; Can be with base body 4 on lens body, base body one end has the zoom ring 2 that eyeglass is housed, and there is draw ring 1 zoom ring end; To realize the vertical pulling zoom; In lens body and zoom ring slip ring 22 is arranged, eyeglass 21 is fixed on the slip ring, can realize zoom, focusing function by the slip ring of passing in lens body or the zoom ring; Focusing, zoom also can be realized by following structure: variant body 23 be a multi-step thread, and the chute 27 that cooperates with screw 26 on the base body 25 is arranged on it, and zoom ring 24 and the screwed connection of zoom body rotate the zoom ring, and the realization of zoom body linear telescopic is focused, zoom.
