Mamiya Sekor Z 50mm f/4.5 W - Mamiya RZ67 Mount

The Sekor Z 50mm f/4.5 W is a wide-angle lens for the Mamiya RZ67, featuring an improved optical design over earlier versions and a floating element system for better close-up performance. It offers a 24mm equivalent field of view, making it a standard choice for architecture and landscape work within the RZ system. The 'W' designation signifies the revised optical and mechanical barrel design. Verification of the floating element ring is essential, as it should move smoothly to ensure sharpness at varying distances. The electronic leaf shutter is controlled by the camera body, so the lens contacts must be in excellent condition. SDS checks for the absence of shutter blade oil and ensures the glass is clear of the haze that can sometimes affect these large-diameter elements.
