Nikon PN-1 &nbsptype_Film Holders The Really Right Stuff MPR-73The Nikon PN 1 is a pre AI extension tube originally designed to provide 1: 1 magnification on the 105mm f4 Micro Nikkor lens. It's designed to mount to pre AI cameras, with a complete lensmount flange, so it may not fit some modern Nikon cameras; the lens side can mount anything F mount, but meter coupling is via the old pin and rabbit ears method. In excellent condition, with light finish wear. Includes rear cap.
