I am looking for the front and rear filter caps for 52 , 58 , 62 , 67 ,72 , and 77 mm .
They are used so you can screw filters of same size together and cap each end to keep dust off .
Right now I am screwing them together and a lens cap on one end and using adapter rings to allow a snap on lens cap to cover other end .
The plastic cases the filters come in take up to much space in camera bag .
Any idea who might still sell them ?
