Overview

The Mamiya / Sekor E 135 mm f/3.5 is a compact medium telephoto lens from the short-lived Mamiya Z/E system. It features a built-in extendable hood and 49mm filter thread. Optically, it is a typical late manual-era lens, but specific performance data is limited; forum users note it is likely a rebadged Tokina design. Its main weakness is adaptability: the aperture ring is a dummy, requiring special adapters for mirrorless or DSLR use. It suits collectors or enthusiasts of the Mamiya Z system who can use native film bodies.
