Manual Focus Operation: Fully manual focusing with no electronic components, keeping the lens mechanically straightforward and repairable.
Medium Format Coverage: Designed to cover the medium format frame used by Mamiya TLR bodies, delivering larger negatives and greater detail than 35mm systems.

Description — Mamiya 105mm f/3.5
The Mamiya TLR 105mm f/3.5 Sekor Lens is a manual focus medium format optic built for the Mamiya TLR mount system, manufactured during the 1960s. As part of Mamiya's interchangeable TLR lens lineup, it offers a 105mm focal length with a maximum aperture of f/3.5, making it a versatile choice for photographers working with Mamiya twin-lens reflex bodies. A key feature of this lens is its integrated leaf shutter, a design approach that places the shutter mechanism within the lens rather than the camera body — enabling flash synchronization flexibility that focal-plane shutter systems cannot match.
Weighing between 400–450g, the lens has the solid, mechanical feel associated with professional medium format equipment of its era. Compatible exclusively with the Mamiya TLR mount, this lens is suited for collectors and working photographers alike who operate within the Mamiya TLR ecosystem.
