This sale is for a mint condition Mamiya RZ67 Extension Tube 82mm (No.2). Both end caps included with this one, so this is a real bargain.
There are absolutely minimal signs of use, just one tiny speck of missing paint on the underside (see photo 3). This tube has been tested and the contacts work perfectly and the ring works fine.
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).
