Mamiya Sekor C 150mm f/4 Manual Focus Lens (USED)

The Mamiya Sekor C 150mm f/4 is a legendary manual focus medium format telephoto prime lens designed specifically for Mamiya 645 camera systems. Renowned for its buttery-smooth bokeh, razor-sharp optical clarity, and exceptional color fidelity, this portrait-length prime delivers the distinctive medium format look that film enthusiasts and digital adopters crave. Whether you are expanding a classic 645 film outfit or adapting vintage glass to modern mirrorless digital bodies, the Sekor C 150mm f/4 offers a perfect balance of reach, compact ergonomics, and timeless mechanical precision.

Precision Optics & Portrait-Ready Rendering

Featuring an ideal short-telephoto focal length (equivalent to roughly 90mm on a 35mm full-frame format), the Mamiya Sekor C 150mm f/4 is built for flattering perspective compression. It naturally renders human features with natural proportions while cleanly isolating subjects from distracting backgrounds. The optical formula utilizes premium multi-coated elements to aggressively control internal flare, ghosting, and chromatic aberrations, yielding crisp contrast and rich tonal depth even when shooting in bright outdoor light.

Robust All-Metal Construction & Manual Control

Constructed with heavy-duty metal lens barrels and smooth tactile focus mechanics, this lens is engineered to endure decades of professional field use. The long, weighted focus throw enables precise manual focus adjustments—a crucial asset for accurate, critical focusing at shallow depths of field. The dedicated manual aperture ring features distinct, reassuring click stops from f/4 down to f/32, providing seamless control for both studio flash setups and natural light photography.

Versatile Medium Format & Adaptability

While native to Mamiya 645 film bodies (such as the M645, 1000s, Super, Pro, and Pro TL), the generous image circle of medium format glass makes the Sekor C 150mm f/4 an outstanding candidate for mirrorless camera adaptation. Using readily available third-party adapters, photographer creators can seamlessly mount this lens to modern Sony E-mount, Fujifilm GF/X-mount, Canon RF, or Nikon Z mirrorless cameras to capture stunning portraits with unmistakable analog character.
