NOTE: Some artifacts in between lens elements, does not seem to affect image quality. The Mamiya 50mm f/4.5 Sekor is a wide-angle prime lens designed for the Mamiya RB67 medium format system. Its 50mm focal length provides a broad field of view on the RB67’s medium format frame, making it well suited for landscape, architectural, and environmental portrait photography. The leaf shutter design allows for flash synchronization at all shutter speeds, providing flexibility for studio and location lighting work. The optical and mechanical construction reflects the build standards typical of Mamiya’s professional medium format lens lineup, and it remains a practical and sought-after option for photographers working within the RB67 system.
