|Expand the potential of your lenses (recent and old) simply by turning them around. A reversing ring has a lens mount on one end which attaches to the camera and on the other end a thread which screws to the filter mount of the reversed lens. Made from metal for a solid thread that won't wear. For use with one lens at a time. A cost effective way of experimenting with macro photography.
Also available for 52mm, 58mm, 72mm and 77mm diameter lenses.
