Detailed Description

Referring to fig. 1 and 2, the stacked filter of the present invention includes at least two filters 10, two adjacent filters 10 are rotatably connected to each other, and two adjacent filters 10 are rotatably overlapped with each other.

After installing lens barrel with filter 10, can switch different kinds of filter 10 through rotating filter 11, or make a plurality of different kinds of filters 10 switch or superpose the use through rotating filter 11, the person of facilitating the use uses, has removed the loaded down with trivial details of dismouting from.

Referring to fig. 2 and 3, according to the first embodiment of the present invention, the filter 10 includes the rotation filter 11 and the assembly filter 12, the assembly filter 12 can be detached from the lens barrel and connected, the rotation filter 11 and the assembly filter 12 and/or adjacent the rotation filter 11 can be rotated and connected, preferably, referring to fig. 3, in this embodiment, the assembly filter 12 is provided with the external thread 121 matching with the internal thread of the lens barrel and connected to the lens barrel detachably. When the filter is used, the assembly filter 12 is installed on the lens cone, and then the rest rotating filters 11 are rotated, so that the filters 10 with different effects are switched, the use is convenient for a user, and the trouble of disassembly and assembly is avoided. Preferably, a rotating shaft 111 is fixed to the mounting filter 12, and the rotating filter 11 can rotate radially around the rotating shaft 111 for switching or stacking.

Under general conditions, after rotating filter 11, can fix the position of filter 10 through the damping, but under the long condition in the practicality, damping between the filter 10 can the undercarriage, leads to taking place relative slip easily between the filter 10, therefore, preferably, between the filter 10 with but magnetism actuation between the adapter ring 20, the adapter ring is provided with magnetic material, filter 10 is provided with magnetic material or can with the material that magnetic material magnetism was inhaled. It should be noted that the material magnetically attracted to the magnetic material includes iron and the like.
