Used Mamiya-Sekor Z RZ67 50mm f/4.5 W | U9

The Mamiya-Sekor Z RZ67 50mm f/4.5 W is a manual-focus ultra wide-angle lens designed for the Mamiya RZ67 platform. It delivers a field of view roughly equivalent to a 24–25mm lens on 35mm full-frame, making it a popular choice for landscapes, interiors, architecture, and environmental portraiture. The lens uses an 11-element, 9-group optical design and features a built-in Seiko leaf shutter capable of flash sync at all shutter speeds up to 1/400 sec. Its close-focusing capability allows focusing down to approximately 0.45m from the front element, giving it surprisingly strong near-subject perspective effects for a medium format lens. The lens accepts 77mm filters, weighs around 760–774g, and measures approximately 97mm in diameter by 82–95mm in length depending on source measurements. Many photographers consider it one of the essential wide-angle options for the RZ67 system, especially for dramatic 6×7 compositions with strong foreground emphasis.
