[0006] The technical scheme of the utility model is as follows: foreground virtualization filter lens assembly, comprising: filter and shell,

[0007] The both sides of the shell are provided with installation groove, the inside rotation of installation groove is connected with hand twist gear,

[0008] The outside of filter is provided with mirror frame, the mirror frame is located in the inside of shell, the both ends of mirror frame are provided with circular slide groove, the both sides in the inside of shell are fixedly installed with circular slide rail, and the circular slide rail and circular slide groove are slidably connected.

[0009] The outer wall of mirror frame is fixedly installed with circular toothed plate, and the circular toothed plate is meshed with the hand twist gear.

[0010] Preferably, the front side of the housing has a circular array of mounting holes, and a circular magnet is fixedly installed inside the mounting holes.

[0011] Preferably, a locking block is fixedly installed at the bottom of the housing, and the locking block is T-shaped.

[0012] Preferably, a circular fixing clip is fixedly installed on the top of the housing, and a hand-twisting thread is provided through the circular fixing clip.

[0013] Preferably, the inner wall of the shell is circular, and the outer wall is irregularly circular.

[0014] The working principle and beneficial effects of this utility model are as follows:

[0015] By manually rotating the hand-twist gear, the hand-twist gear drives the meshing circular toothed plate to rotate, and the linked lens frame rotates on the circular slide rail through the circular groove, causing the filter to rotate. This rotation of the filter achieves the purpose of blurring the moving foreground in the camera, improving the bokeh effect. Attached Figure Description
