This sale is for a really excellent condition Mamiya RZ67 Extension Tube 82mm (No.2).
There are minimal signs of use, just a little lost paint on the back edge of the front ring. This tube has been tested and the contacts work perfectly and the ring works fine. Please note that no end caps are included with this tube.
This extension tube will give you 0.65 to 1.01x magnification with a standard 127mm lens. With the No. 1 tube I am also selling, you can get to 1.36x magnification with a 127mm lens.
A copy of the instruction leaflet can be downloaded from the Downloads section of this website that gives full details of usage (essential for correct exposure if you do not have a metered finder).
