COKIN 55-55mm közgyűrű

The Cokin common ring essentially works as a spacer ring. The spacer ring must be screwed into the filter holder of the lens, then the Cokin filter holder adapter ring can be screwed into the ring. In this way, a sufficient distance is created between the lens and the filter holder frame to comfortably use, for example, the Cokin macro front lens with an even smaller object distance.
