Mamiya Sekor C 45mm f/2.8 - Mamiya M645-mount

The Sekor C 45mm f/2.8 is a wide-angle lens for the Mamiya M645 system, providing a field of view roughly equivalent to a 28mm lens in 35mm format. It is valued for its compact size relative to its wide aperture, making it a versatile choice for landscape and architectural photography. The lens uses a manual focus design with a 67mm filter thread. Used examples should be checked for smooth focus ring movement, as the damping grease can stiffen over time. We inspect the aperture blades for snappy operation and the absence of oil. As with many older Mamiya manual focus lenses, it is important to check the rear element for any cleaning marks or scratches that could affect contrast.
