TAKUMAR A 28MM F2.8.  PK MOUNT. EASILY ADAPTED TO MANY DIGITAL FORMATS.  USED AND FULLY TESTED ON MY DSLR. CAMERA AND ADAPTER NOT INCLUDED. HARD TO FIND BETTER.  REALLY LOVELY. SELLING MY COLLECTION,  DOWN TO ABOUT 25 LENSES. NOW INTO MY BELOVED PENTAX SELECTION. SOME I'VE HAD SINCE 1966. SEE FEEDBACK BUY WITH CONFIDENCE. MY ADVICE IF LOOKING FOR VINTAGE LENSES TRY PENTAX OR ZEISS ESPECIALLY IN M42. GREAT VALUE AND WERE TOP RATED IN 60s AND 70s. GET 1 M42 AND PK ADAPTER AND YOU'RE GOOD TO GO. *UK ONLY* IF NOT SATISFIED JUST RETURN.  CAPS INCLUDED.  **UK ONLY**
