    Overview

    The Mamiya Sekor K/L 180mm f/4.5 is a lightweight medium format lens (under 650g) praised for its compactness and near-macro capability at 1.1m focus. Its slow aperture suits daylight or fast film, but it lacks low-light performance. Build-wise, mounting on auto-cocking bodies can be tricky due to a misaligned cocking lever, and accidental shutter firing is possible. It is ideal for walk-around daylight shooting, especially on Mamiya TLRs like the C220, but less suited for action or low-light work.
