If you mean the ML series, they are, for the most part good performing lenses and a great value. Except for a few German made ones, the Contax lenses and Yashica lenses were made by Kyocera in Japan. Now I'm NOT saying the Contax 35 and Yashica 35 are identical, but instead that there may not be much difference. Maybe some other PN members who have used both lenses will give their impression of these lenses.
