The Kiwifotos BR-52NK is a filter ring that mounts into the rear of a NIKON mount lens. It provides 52mm threading for filters and other front attachments when the lens is reversed.
You will need to already have a lens reversal ring (such as a JJC RR-2A or RR-52AI) but you can then add effects to you macro shots.
When using automatic diaphragm is not available, so 'stop-down' metering has to be used.
