Hold the Ring in the palm of your hand with the two grips facing upwards. Place the Polarizer into the ring and screw in a clockwise direction until secure.
Slot one clip from the Polariser Ring into the slot on the front of the holder. Snap the clip on the other side into place.
Polarizer will be held securely in place, and the Holder can be attached to the Adaptor Ring. Any other filters can then slide into the Holder in the normal way.
