Yes, the Rolleinar 135/2.8 is the Mamiya-Sekor sx 135/2.8 design, however multi-coated. Several Rolleinar/Mamiya lenses were made by Rollei Optical Co. at Singapore up to 1981 according an agreement Rollei-Mamiya. Claus Prochnow (the Rollei Report books author and Rollei engineer for 37 years) wrote me in 2007: " Hello Carlos The Mamiya lenses are manufactured first in Japan, later in Singapore by Rollei. It was sheaper than in Japan. Kind regards Claus" I also have the Voigtländer Color Ultron AR 1.4/55mm lens, multicoated, this is the Rolleinar/Mamiya 1.4/55 MC labeled Color Ultron for the Voigtländer cameras made by Rollei The Mamiya, Rolleinar and Color Ultron versions are a copy from the CZ Planar 1.4/55mm made for the Contarex.
