Nikon BR-2 Lens Reversing Ring
This ring enables a lens with a 52mm diameter to be reverse mounted, either directly to the camera, or to a bellows unit. The thread is a male F-Bayonet and is designed without diaphragm or meter coupling.
The ring is in excellent used condition - box is in good condition with shelf wear.
An excellent opportunity to get a great macro accessory!
Thanks for looking!
