Lens diameter 52mm - filter diameter 67mm.
Used to mount filters or pre-filters on lenses if the filter dimension is different than the lens dimension.
Reducing rings (also called step up or step down rings) are used to attach filters or pre-filters to lenses when the filter dimension is different from the lens dimension. Thus, they allow you to use one filter/pre-adjustment on multiple lenses. The first is the lens dimension, the second the filter dimension in mm.
