Another thrift shop find, this Yashica 50mm 1.4 lens optically and mechanically in good condition, but has several cosmetic 'dings' and 'scuffs' at the front of the lens. However, I had no problem screwing-on a 52mm UV filter in front of the lens despite the damage (see photo below).

Info for this lens in particular at: http://allphotolenses.com/lenses/item/c_436.html#prettyPhoto
The photos captured below were taken 'as-is" with the subject lens on a Samsung NX1, no filters were employed and there was no post-editing or effects added to the images.
