Abstract

The invention discloses a fish-eye lens. The fish-eye lens comprises a frame and a lens assembly which is arranged in the frame, wherein a circular polarizer is combined in the lens assembly; the fish-eye lens is detachably arranged on a lens of external equipment through a mounting structure and can rotate freely along the circumference. According to the fish-eye lens, by additionally arranging a circular polarizer in the lens assembly, unnecessary polarized light is removed, so that the entire picture is clearer, a more transparent feeling is realized, the problem of reflection during photographing is solved, and the photographing effect is clearer; the fish-eye lens is detachably arranged at the lens position of external equipment through the mounting structure, so that free rotation of the fish-eye lens along the circumference is guaranteed.

Description

technical field [0001] The invention relates to a fisheye lens, in particular to a fisheye lens capable of eliminating reflection. Background technique [0002] The number of pixels supported by CCD (Charge Coupled Device) in various existing external devices equipped with cameras (such as video phones, video phones, digital cameras, video cameras, cameras, etc.) is constantly increasing, and some products have already surpassed The number of pixels supported by a professional digital camera. [0003] The angle of view of a general camera when taking photos is limited by the lens. In the field of professional photography, there is a fisheye lens that can be added to the front of a professional digital camera for panoramic image shooting with a large viewing angle. The imaging characteristics of the fisheye lens are A lens with a large viewing angle close to or equal to 180°. [0004] Although the fisheye lens can increase the angle of view when shooting, it often encounter...
