This sale is for a near mint condition Mamiya RZ67 90mm f3.5 W lens, boxed and including both caps and the original instructions.
This lens is in near mint with absolutely minimal signs of use. It is optically perfect other than minimal haze that will have no effect on your images – virtually all RZ67 lenses are like this now simply due to age. The lens is in perfect working order, including both flash sync and mirror up release.
A superb lens, and now really hard to find.
