Mamiya Sekor Z 250mm f/4.5 W - Mamiya RZ67-mount

The Sekor Z 250mm f/4.5 W is a telephoto lens for the Mamiya RZ67 system, offering a 35mm equivalent focal length of approximately 120mm. The 'W' designation indicates a later, improved optical design and enhanced mechanical reliability. It is a popular choice for fashion and portrait photography where a narrow field of view and flattering compression are required. As with all RZ67 lenses, the electronic leaf shutter must be tested for accuracy across all speeds. Inspect the rear electrical contacts for corrosion or wear, as these are vital for communication with the camera body. SDS checks for internal haze and ensures the aperture blades move swiftly. The barrel should be free of significant impacts that could affect internal alignment.
