Overview

The Mamiya-Sekor E 135 mm f/3.5 is a compact medium telephoto lens from the short-lived Mamiya Z/E system, featuring a built-in extendable hood and 49 mm filter thread. Its aperture ring is a dummy, requiring a special adapter for aperture control on mirrorless cameras. Optical performance is not detailed in the excerpts, but the lens is noted as a typical late manual-era design. It suits photographers interested in adapting vintage Mamiya glass, though adapter availability is limited. No optical strengths or weaknesses are mentioned.
