Nikon BR-2, BR-3 & BR-4 Macro Reverse Adapter Ring Set Lens adapter

Set of original Nikon macro accessories for close-up and macro photography with reversed-mounted lenses.

The set consists of:

* Nikon BR-2 reversal ring
* Nikon BR-3 adapter ring
* Nikon BR-4 automatic diaphragm ring
* Nikon F-mount connections
* Made in Japan

With the BR-2, a lens with a 52mm filter thread can be mounted in reverse on a Nikon camera or bellows unit. This enables strong macro magnifications. The BR-3 and BR-4 are used for further connection and operation of a reversed-mounted lens. The BR-4 is provided with a connection for a double cable release.

The set consists entirely of mechanical adapter parts and contains no optical glass. The parts are used and show normal signs of aging and wear.
