The BR-2A enables you to mount a 52mm front thread lens in reverse on the PB-6 and Nikon cameras. This increases magnification and working distance. BR-3 provides a 52mm thread for filters and other lens attachments with lens in reverse. BR-5 allows mounting lens with 62mm thread (use with BR-2A). BR-6 for the PB-4, PB-5 and PB-6 enables Nikkor lens auto-diaphragm control with BR-2A BR-3 AR-4/7/10 cable release.

Using F mount ring on a bellows on a d90 and a d70 where I don't need light meter coupling. Pure manual set up. Satndard 70-300mm produces excelent macro images.
This is a very easy to use sturdy,and very well made product. Serves the purpose of why I bought it(for Macro photography). Love it
When you're looking to reverse your lens to get some serious macro magnification, this is a really valuable accessory. In effect, it turns the rear of your lens into a 52mm filter thread so you can add filters, lens hood etc. Simple to use and valuable accessory.
