Near MINT Mamiya Sekor C 55mm f/2.8 MF Manual Focus Lens 645 1000S Pro TL JAPAN

Mamiya 645 MountThe Sekor C 55mm f/2.8 is designed for Mamiya's interchangeable-lens manual focus system, compatible with 645 camera bodies including Mamiya 645, M645, Pro, TL, and Super models. This mount enables the characteristic modular design of Mamiya 645 cameras, allowing photographers to swap lenses and film backs independently. Optical DesignThe 55mm focal length on Mamiya's 645 format (6x4.5) delivers a normal perspective slightly wider than a 50mm on 35mm film. The f/2.8 maximum aperture provides adequate light-gathering for hand-held rangefinder work while maintaining a compact form factor typical of the 645 lens lineup. Mechanical ConstructionLike all Mamiya 645 lenses, the Sekor C 55mm features a helicoid focusing mechanism with smooth manual focus control. The lens integrate.
