This sale is for a really mint condition Mamiya RZ67 180mm f4.5 W-N telephoto lens, suitable for use on any Mamiya RZ67 cameras, and including both caps.
This lens in is perfect mechanical, optical and cosmetic condition; fully tested and of course it works perfectly. There are no signs of use that I can see. It certainly cannot have been used more than a few times.
You will not find a better example. Equivalent to about 87mm in 135 format – the perfect portrait lens.
