Here is the beautiful 180mm f2.8 manual focus lens with extra low dispersion glass. It is the best manual focus prime in this range and is a perfect video lens. This lens has several blooms of fungus toward the edges. These should not effect image quality. Otherwise the lens is in excellent condition with clear glass and the focus and aperture are smooth. There is an ID number engraved on the bottom of the focusing ring but it is subtle and I did not notice it at first.
