    I bought this lens new about l979 from Spiratone. It can be handheld at 500 sec. I have used it on Contax/Yashica and Pentax K mount cameras. It can be mounted on any brand camera with a T-mount adapter. It is indeed very sharp, and its reproduction of colors is indeed quite beautiful. I have taken outdoor “portrait” type shots of people in relaxed poses at picnics, ballgames, etc. and the results are equal if not better than the well known name brand camera lenses. It has Plura-Coat lens coatings.
