Saga Dive Single Flip Diopter Holder M67
67mm threaded macro diopter lens holder. Easy and convenient to swing a macro lens onto the port of an slr or compact housing. Screw ring is tightened using spanner (included) onto any 67mm threaded port, then the macro lens is screwed onto the flip-out holder. Allows you to instantly add and delete a macro lens without unscrewing it. Machined, anodized aluminum. Has internal spring tension to hold in either open or closed position. Works with most 67mm threaded ports, but must be deep enough to attach.
