二手 Nikkor Nikon F BR-3 轉接環（用於蛇腹對焦配件）

Got this to replace a missing part for my bellows setup, and the threads are perfectly clean—no wobble when mounting. Works exactly as needed for macro work.

Finally found a genuine Nikon BR-3 ring to complete my bellows setup—the threads are smooth and it fits perfectly without any wobble. It arrived in clean used condition with no noticeable wear, exactly what I needed for macro work.

The threads on this BR-3 ring seat perfectly into my bellows unit, no wobble or play at all. Arrived clean and solid, exactly what I needed to lock the adapter setup down.
