Vipesse Reverse Ring for Nikon

To use this Nikon Reversing Ring simply clip one side into the Nikon body and then screw in the 67mm camera lens to the reversing ring thread. 

With a lens mounted on a camera in the normal position the image of a large object is reduced in size so that it can be recorded on the sensor or film. When the lens is mounted in reverse (using a reversing ring), the opposite happens. Small objects are recorded at life-size or enlarged.
