This sale is for a really excellent example of the Mamiya 645 35mm f3.5 C lens – fully working.
This ultra wide angle lens (equivalent to about 21mm on a 135 camera) only very minor signs of use. It is cosmetically near mint with just typical paint loss on the mount. It has superb glass except for faint haze, but this is very minor and there will be no effect on normal images. Possibly a little flare if you shoot directly into the sun, but otherwise fine. There are no mechanical or other optical issues at all with this lens.
Overall a really nice lens. Not an easy lens to find. Low price for one of these lenses due to the slight haze.
