The filter or the filter component is connected to the lens through the bracket, and the bracket is connected with the lens through the switching device. The filter or filter assembly may also be attached to the lens directly by the adapter. The common switching device is a switching ring, the sizes of lenses of different manufacturers and different wide angles are different, and the lens of one size needs to be installed through one switching ring. For lenses of different sizes, the photographer needs to use adapter rings of different sizes. Therefore, the photographer usually purchases a plurality of adapter rings with different sizes to match the lenses with different sizes, which undoubtedly increases the cost expenditure of the photographer. In addition, when a photographer goes out to shoot, in order to match lenses with different sizes, the photographer needs to carry a plurality of adapter rings with different sizes, which is very inconvenient.
In short, the adapter ring has the following drawbacks: high replacement cost, poor universality and inconvenient carrying.
