Overview

The Auto Mamiya-Sekor CS 28mm f/2.8 is a vintage M42 wide-angle lens offering a classic 28mm field of view and f/2.8 aperture. Optically, it delivers very good center sharpness and contrast, but corner sharpness could improve when stopped down. Its rendering prioritizes mood over perfection, with gentle corner roll-off and warm color. Build is lightweight at 170g with a 49mm filter thread. It suits photographers seeking a characterful, manual-focus lens for street, documentary, or cinematic work on mirrorless bodies via adapter.
