    Overview

    The Auto Mamiya-Sekor CS 50mm f/1.4 is a vintage standard lens praised for its color rendering, contrast, and deep blacks. It is sharp wide open with beautiful bokeh and approaches the performance of the Zeiss Planar 50mm f/1.4, though a small difference exists. Weaknesses include limited sharpness compared to modern glass and struggles in low light. Build is all-metal with a tactile aperture ring, but focus can be tight. It suits purists and those seeking a characterful vintage lens on mirrorless or M42 cameras.
