Abstract: A handle mechanism includes a front grip and a rear grip, wherein the rear grip is hinged with the front grip, and the rear grip is provided with a mounting assembly for mounting the rear grip on a side of an external photographic device. The front grip and the rear grip can be rotated and fitted together so as to be used as a handle of the external photographic device. The handle mechanism serves as a desktop support, and the front grip and the rear grip can b e rotated and unfolded to form a V-shaped support to support the external photographic device. The handle mechanism may be configured as a handle and a support. Compared with a handle and a support that are independent, the handle mechanism is more convenient to carry and use, and has a lower use cost.

Abstract: A matte box assembly has a body that allows an optical filter to be installed at the frontmost portion of the body. The matte box assembly has a lens coupler that can couple the body to a lens without causing damage to the lens. The matte box assembly has a flag that can pivot against the body to shield light from a desired direction. The matte box assembly provides various attachment points for accessories.

Abstract: A camera matte box electrically controls an adjustable lens filter. The camera matte box includes a body, at least one adjustable flap, a filter holder, a changeable lens adapter, and an electrical filter control module. The electrical filter control module adjusts a position of the adjustable filter according to a command received using a communication interface. The filter holder removably holds the adjustable filter and a non-adjustable filter in the body.

Abstract: A camera lens support system distributes the weight of a lens in a camera rig. The camera lens support system provides multiple degrees of freedom and adjustment to support a large number of lens and camera body combinations. The camera lens support system includes a locking mechanism that can simultaneously restrict translational and rotational adjustments of the camera lens support system.

Abstract: A camera mount that can provide high stability, ease of operation, and flexible configurations for different applications and installation scenarios. The camera mount has an improved attachment mechanism that provides multiple locking positions and strengthened positioning pins. The camera mount has a plurality of anchoring devices capable of securing the camera mount on different curved surfaces.

Abstract: An electronic viewfinder (EVF) can be operatively connected to a camera using a flexible EVF extension system that allows the use of the EVF at a large number of positions relative to the camera. The flexible connection system can be used in various configurations that can mitigate the difficulty of using the EVF in different shooting scenarios. The EVF enables a photographer to operate a camera in a large number of shooting scenes to achieve various shooting effects with ease.
