Nikon PN-11 iso_125 so we do not recommend

so we do not recommend that you buy it with the expectation that it's a turnkey Rolleiflex

The lens (a "factory" AI conversion) is clean

Nikon PN-11 iso_125 so we do not recommendThe Nikon PN 11 is a 52. 5mm extension tube originally designed to provide 1: 1 magnification on the 105mm f4 Micro Nikkor lens. That said, you can use it with any Nikon F lens for extra macro magnification. And unlike other Nikon tubes, the PN 11 has a rotating tripod mount for extra stability, which is extremely useful. In excellent condition, with light cosmetic wear.
