This sale is for a complete set of genuine Mamiya 645 Auto Extension Rings No. 1, 2 and 3-S to fit all of the Mamiya 645 manual focus cameras – M645, M645J, 1000S, 645E, Super, Pro and Pro TL. These rings are all in mint condition with absolutely minimal signs of use, just one small suff on the inside of the No. 1 tube (see photo # 4).
These extension rings are in perfect mechanical condition, but please note that the end caps are not included. Apart from that there is not a lot to say – the aperture controls work perfectly and the rings work fine. A superb set of extension tubes.
These extension tubes will take you all the way from 0.15 (No.1 ring alone) to 1.04x (if you use all three together) magnification with a standard 80mm lens.
I tend to use these rings just to get a closer focus with my 150mm and 210mm lenses – they are so small that they are no problem to carry around in case you need it.
