Description — Mamiya 55mm f/4.5
The Mamiya TLR 55mm f/4.5 Sekor Lens is a vintage medium format optic produced during the 1960s, built for use on Mamiya TLR cameras via the dedicated Mamiya TLR lens mount. Designed for Medium Format 120 film, it slots into the interchangeable lens system that made Mamiya's TLR lineup particularly versatile among medium format shooters of its era. The lens operates with manual focus and is equipped with a leaf shutter, a design that provides reliable flash synchronization capability — a genuine advantage for photographers working with strobes or flash units.
Weighing between 400g and 450g, the lens has the substantial, solid feel expected of professional medium format glass from this period. With a maximum aperture of f/4.5, it is well-suited to controlled lighting environments. For collectors and working film photographers seeking authentic 1960s Mamiya TLR glass, this Sekor lens offers a direct connection to medium format photographic tradition.
