Abstract

The invention relates to a filter holder set, which is installed on a camera or a camera lens. The front end port of the lens has an internal thread for connecting a UV mirror. The filter holder set includes a filter holder, a connecting plate, And the connection ring, the filter holder is rotatably connected to the connection plate, the connection plate is detachably connected to the connection ring, and the connection ring is connected to the internal thread of the UV mirror at the front end port of the lens. Lens threaded connection. The filter holder kit of the present invention is more versatile, and can avoid the defect of being unable to connect and install due to different lens brands; and the filter can be corrected to make photography more accurate. And it is realized that the filter holder is directly installed at the connection of the UV mirror at the front of the lens, closer to the lens, so that the light shifts less, produces better photographic effects, and avoids affecting the viewing angle of the wide-angle lens.
