Instant purchase welcome. [Appearance] There are small paint imperfections due to age, but there are no noticeable scratches or stains. Please check the photos. [Optics] There is some minor dust, but there is no mold or fogging that would affect shooting. When a strong light from an LED penlight is shone through, slight coating unevenness can be seen, but I don't think it's at a level that would affect shooting. [Operation] The aperture and helicoid movements are smooth and there are no problems. [Included Accessories] The original metal hood, a Kenko filter, and a generic rear cap are included. [Sample Photos] The ninth photo was taken with this lens using a mirrorless single-lens reflex camera. [Other] Although it says K-mount because there is no relevant category, it is actually an M42 mount. #PENTAX #LargeAperture #OldLens #FullFrame #StandardLens #ScrewMount
