A size-adjustable lens filter support comprises a lens clamping base (1) and a lens mounting frame (2) that are connected as a whole. Two or more arc movable clamping elements (3) are embedded in the sidewall of the inner side of the lens clamping base (1), and a regulation thread hole (4) and a regulation screw (5) are disposed on the sidewall of the outer side. The regulation screw (5) is movably screwed into the regulation thread hole (4), and the tail end of the regulation screw (5) is rotatably connected to the corresponding clamping element (3). The regulation screw (5) is manually regulated to drive the clamping elements (3) to move inward or outward, so as to match photographing device lenses of different sizes; the support is manually operated and fastened, thereby effectively avoiding the problem that a housing of the lens is deformed and damaged due to an excessively great clamping force. In addition, the lens mounting frame (2) can be rotatably connected to and integrated with the lens clamping base (1) in a 360-degree rotation manner, and accordingly, the lens mounting frame (2) enabling 360-degree rotation can be equipped with a high-definition CPL polarizer, thereby achieving a CPL light polarizing function. The size-adjustable lens filter support has high versatility, and is flexible in use and convenient to operate. |
