Cokin CBP40077 P-Series Holder with 77mm Adapter Ring
The COKIN CREATIVE SYSTEM consists of 3 main components: An Adaptor Ring + A Filter Holder + 1 or more filters.The COKIN Filter-holder can be precisely adjusted and attached to the lens by means of a screw-in adaptor ring. A change of camera or of lens necessitates only a change of adaptor ring, not the Filter-holder nor the filters.The COKIN Filter-holder has four grooves. One holds round filters, which can be rotated in the groove. The three others hold square filters which can be adjusted up or down at will.
