This sale is for a near mint condition latest version Mamiya 645 45mm f2.8 N lens, including both caps.
This lens in is perfect mechanical and optical condition; no problems at all, aperture really fast without any sticking. Cosmetically it is mint other than the usual very minor wear on the lens mount, but this is unavoidable if you actually use the lens. This is a superb lens, equivalent to 28mm in 135 format.
A really nice lens, and not at all easy to find in this condition. Everybody wants wide angles at the moment!
