Mamiya/Sekor Auto SX 28mm f/2.8 Lens for M42 Mount

The Mamiya/Sekor Auto SX 28mm f/2.8 is a manual focus wide-angle prime lens produced for M42 screw mount cameras. At 28mm with an f/2.8 maximum aperture, it delivers a moderate wide-angle field of view well suited to landscape, architecture, interior, street, and environmental photography, with useful light gathering capability for shooting in lower light conditions. The Auto SX designation indicates an automatic aperture mechanism that stops down to the set aperture only at the moment of exposure, allowing the viewfinder to remain bright during composition and focusing. Fully manual focus operation covers focus adjustment directly on the lens. Compatible with M42 screw mount film SLR bodies, and adaptable to a broad range of mirrorless and other camera systems via standard M42 adapters.
