The present disclosure relates to the technical field of magnetic filter equipment, and in particular to a nonferrous magnetic filter system.
In the photography, attaching a filter into a camera lens can filter out a part of light or eliminate the reflections from a surface of an object to create a special photography effect, reaching a best photography effect. Meanwhile, in order to reach different shooting purposes, changing different types of filter lenses according to different requirement is practicable.
The existing way of mounting a filter includes using a spring clamping, an adapter ring connection or a magnetic adsorption. As a relatively novel method for mounting the filter, the magnetic adsorption still remains many disadvantages. For example, in the existing magnetic filter mounting assembly, parts that attracts the magnet are made of ferrous material. However, the ferrous material is heavy in mass, the parts are easy to fall from the lens, overloading and offsetting the lens. Besides, the ferrous material is easy to get oxidized when exposed in the air, lowering a service life of the magnetic filter mounting assembly, and the oxidized ferrous material will make an appearance of the magnetic filter mounting assembly unsightly.
The present disclosure provides a nonferrous magnetic filter system, aiming to solve a defect in the related art.
