Mamiya-Sekor E 135mm f/2.8 | Good Condition | The Sharpest Portrait Prime of the CS System

The Mamiya-Sekor E 135mm f/2.8 is a high-performance telephoto prime lens designed for the Mamiya NC and ZE series 35mm SLR cameras. Renowned for its exceptional sharpness and robust build quality, this lens is a dedicated portrait specialist. The 135mm focal length provides a beautifully compressed perspective that is incredibly flattering for headshots, while the fast f/2.8 aperture allows for superb subject isolation and a smooth, natural background blur (bokeh). As part of the "E" series, it features electronic signaling for advanced exposure modes on compatible Mamiya bodies, making it a sophisticated choice for both analog purists and vintage lens adapters.

Specialist Note "The Mamiya-Sekor E 135mm is often overlooked, but it is one of the sharpest 135mm lenses produced during the 1980s. Mamiya’s expertise in medium format optics clearly bled into their 35mm glass; the resolution and micro-contrast on this lens are outstanding. It has a built-in lens hood that is very convenient, and the mechanical feel of the focus ring is buttery smooth. For anyone adapting lenses to mirrorless systems, this 135mm offers a professional, high-end look that competes with much more expensive Japanese primes."

Condition Report Good condition. The lens barrel shows normal signs of light use and minor surface wear consistent with its age. The optics are clear, with no signs of fungus, haze, or significant scratches. The aperture blades are clean and snappy, and the manual focus ring operates with consistent, smooth resistance.
