Selling my MINT- Condition 105mm 1.8 Ais lens. Focus is firm and buttery smooth (Noctilux like), glass has no marks whatsoever and no scratches or marks on lens. Light internal dust visible in very bright lighting (flashlight shined through) and very slight wear on two of the 9 aperture blades. Otherwise a very nice copy indeed! Nicest manual focusing lens I have ever used.
