Installing a filter on a camera lens, adjusting an aperture, and rotating the lens to enable a high light point to be out of focus; at the moment, due to the shading effect of the opaque part, the highlight points form scattered focal spots on the photo; it has the advantages of convenient manufacture, low price and wider application range.
Description
Technical Field
The utility model relates to a photographic technical field, especially a filter, camera lens subassembly and camera.
Background
The photographer can create a "donut" defocused spot effect on the photograph using a catadioptric lens. The catadioptric lens is unique in that: when the high light spot outside the depth of field is out of focus (i.e. virtual focus), the high light spot does not become a common light spot on the picture as a common long-focus lens is imaged, but presents small circles with different sizes. But the imaging of the catadioptric lens is not clear enough; only the first-level aperture can not adjust the size of the aperture. Therefore, in order to take a better quality picture, the photographer often has to give up with the catadioptric lens and the "donut" defocus effect.

If the first and second are described for the purpose of distinguishing technical features, they are not to be understood as indicating or implying relative importance or implicitly indicating the number of technical features indicated or implicitly indicating the precedence of the technical features indicated.
In the description of the present invention, unless there is an explicit limitation, the words such as setting, installation, connection, etc. should be understood in a broad sense, and those skilled in the art can reasonably determine the specific meanings of the above words in combination with the specific contents of the technical solution.
Referring to fig. 1, an embodiment of the present invention provides a filter including a lens 100, the lens 100 being provided with an opaque member 110 for forming an astigmatism spot on a photograph.
In this embodiment, the filter is mounted on the camera lens, with a telephoto lens being the most preferred. Adjusting an aperture, and rotating a lens to enable a high light point to be out of focus; at this time, the highlight dots form scattered spots on the photo due to the light shielding effect of the opaque member 110. The filter has the characteristics of convenient manufacture and low price, and only needs to be processed on a common filter. The filter can be mounted on various lenses, but when the catadioptric lens is mounted on the camera, other lenses cannot be mounted. Compared with a catadioptric lens, the filter has wider application range, and enables the quality of pictures shot by photographers to be better and more diversified.
Preferably, in the present embodiment, the lens 100 is a transparent lens with uniform thickness.
In one aspect, opaque member 110 is an opaque film formed by coating lens 100.
On the other hand, the opaque member 110 is an opaque ink layer formed on the lens 100 by silk-screening.
In yet another aspect, the light-impermeable member 110 is a plastic block that is secured to the lens 100. The plastic block may be secured to the lens 100 by an adhesive. Alternatively, a through hole is cut in the lens 100, and a plastic block is mounted on the through hole. Of course, in other embodiments, the opaque member 110 may be made of other opaque materials.
Further, the filter further comprises a frame 200, and the lens 100 is fixed in the frame 200. In addition, the outer side surface of the frame 200 is provided with a screw thread. The filter can be screw-coupled with the lens through the screw of the outer side of the lens frame 200.
Specifically, the shape of the opaque member 110 is circular, the opaque member 110 is located at the center of the lens 100, and the lens 100 is a circular lens 100. This shape structure will form the most commonly used annular defocused spot on the photograph taken. Of course, in other embodiments, the lens 100 can be other shapes, such as square. The shape of the light-impermeable member 110 may be other shapes such as square, star, etc. The light-impermeable element 110 can be placed anywhere on the lens 100. It should be noted that the position and shape of the opaque member 110 will appear on the defocused spot, that is, the shape of the darker shaded surface in the defocused spot is the same as the shape of the opaque member 110, and the position of the darker shaded surface in the defocused spot is the same as the position of the opaque member 110 in the lens 100.
The utility model discloses a lens assembly is provided to another embodiment, including the camera lens with as above the filter, the filter is installed on the camera lens. The lens is preferably a telephoto lens
Another embodiment of the present invention provides a camera including the lens assembly as described above.
The lens assembly provided with the filter is arranged on a camera, so that a picture with special defocusing spot effect can be shot.
The above description is only a preferred embodiment of the present invention, and the present invention is not limited to the above embodiment, and the technical effects of the present invention can be achieved by the same means, which all belong to the protection scope of the present invention.
