Camera capable of rapidly replacing optical filter

The invention belongs to the technical field of cameras, particularly relates to a camera capable of quickly replacing an optical filter, and provides the following scheme aiming at the problems that when an optical filter in an existing camera is replaced, a camera shell generally needs to be disassembled and replaced, the operation is tedious, frequent replacement easily causes much dust on the optical filter, and the shooting effect is affected. The front side of the shell is provided with an eyepiece, the rear side of the shell is provided with a lens, the inner wall of the shell is provided with an aperture plate, one side of the aperture plate is rotatably connected with a mounting plate, the mounting plate is provided with a plurality of placing holes, the placing holes are internally provided with fixing rings, the fixing rings are provided with optical filters, and the optical filters are arranged on the fixing rings. And a clamping mechanism is arranged on the mounting plate. The device is easy to o
